Both of the water-repellent portions exposed so that the resin comes into contact with the outside air have a structure in which both are microscopically dispersed on the surface, and the surface is substantially transparent with a contact angle of 90 ° or more with water. A cover for a motorcycle instrument panel having a water droplet adhesion-preventing property characterized by having a surface layer formed thereon. A structure in which both a hydrophilic part exposed to contact the photocatalytic oxide particles with the outside air and a water-repellent part exposed to the water-repellent fluororesin contact with the outside are microscopically dispersed on the surface. In this case, since the hydrophilic surface and the water-repellent surface are adjacent to each other, the hydrophilic adherent that easily adapts to the hydrophilic surface does not adapt to the adjacent water-repellent portion. Conversely, hydrophobic deposits that are easily adapted to the water-repellent surface do not adapt to adjacent hydrophilic portions. Therefore, neither the hydrophilic deposit nor the hydrophobic deposit is fixed to the member surface, and the surface is maintained in a clean state. Furthermore, the presence of a photocatalyst
Since the photocatalytic oxide particles exposed in contact with the outside air in response to the photoexcitation of the photocatalyst maintain the hydrophilic portion permanently, both the hydrophilic portion and the water-repellent portion are present. A structure that is microscopically dispersed on the surface is maintained. That is, if the contact angle with water on the surface is set to 90 ° or more during the production of the surface layer during the production of the surface layer, the state is maintained in accordance with the photoexcitation of the photocatalyst, and water droplets hardly adhere. Therefore, it is possible to prevent the fogging inside the cover in cold weather or rainy weather and the adhesion of discrete water droplets outside the cover, thereby ensuring the safe driving performance in cold weather or rainy weather.

The coating liquid obtained by stirring for 30 minutes is applied on a soda lime glass substrate of 10 cm square by a spray coating method and heat-treated at 380 ° C. for 3 minutes to form an anatase-type oxidation. A surface layer composed of 4 parts by weight of titanium particles and 6 parts by weight of polytetrafluoroethylene particles was formed to obtain a # 1 sample. #
1 Observation of the surface of the sample shows that both the photocatalytic oxide particles exposed to be in contact with the outside air and exhibit a hydrophilic property and the water-repellent fluororesin exposed to be in contact with the outside have water repellency. It was confirmed that a surface layer having a structurally dispersed structure was formed. Next, the contact angle of the surface of the # 1 sample with water was measured. Here, the contact angle with water was evaluated using a contact angle measuring device (Kyowa Interface Science, CA-X150) based on the contact angle with water 30 seconds after dropping. As a result, the contact angle with water becomes 120 ° and a value of 90 ° or more,
When the # 1 sample was tilted, the water droplets fell while rolling. Next, using an ultraviolet light source (Sankyo Electric, Black Light Blue (BLB) fluorescent lamp) on the # 1 sample, 0.5
The sample was irradiated with ultraviolet rays at an ultraviolet illuminance of mW / cm 2 for about 1 day to obtain a # 2 sample. The contact angle with water was measured for the # 2 sample. As a result, the contact angle with water became 110 ° and a value of 90 ° or more. When the # 2 sample was tilted, the water droplets fell while rolling.
