The convex portion 11a of 1 has a tapered shape. Therefore, each convex portion 11a is more easily melted by heating, and the adhesive ability of each convex portion 11a can be developed quickly and easily, and the adhesive force between the base material 11 and the skin 12 can be shortened. There is an advantage that can be sufficiently secured. Further, in the door trim 10, since the base material 11 is configured to have the convex portions 11a on all the surfaces (adhesion surfaces) to which the outer skin 12 is adhered, the back surface folded-back portion of the outer skin 12 is also provided with the adhesive. There is an advantage that it can be adhered to the attachment surface on the back side of the base material 11 without intervening.

A breathable foamed molded body having a large number of open cells is adopted as 1, and a non-breathable skin is adopted as the skin 12. Therefore, when the epidermis 12 is attached to the adhering surface of the base material 11, a negative pressure is applied to the epidermis 12 through the base material 11 and the epidermis 12 is attracted to the adhering surface of the base material 11 by its suction action. Therefore, there is an advantage that the strong adhesion between the base material 11 and the skin 12 can be completed in a short time. In this case, between the convex portions 11a of the base material 11 functions as a dispersion groove that evenly distributes the negative pressure, and the base material 11 of the skin 12 is provided.
There is an advantage that the suction action to the sticking surface of is further improved.

From the sticking surface of the base material 11 and the epidermis 1
It is possible to manufacture the door trim 10 in which the adhesive strength between the base material 11 and the skin 12 is high and the adhesion is uniform between the two adhering surfaces. Thereby, the high quality door trim 10 can be provided by the manufacturing method.
