A hearing aid case is usually composed of a plurality of case members molded from synthetic resin, and naturally there are joints between the case members. Although this joint is said to be tightly joined, moisture such as sweat and rain can enter the hearing aid case through the joint due to capillary action, causing insulation deterioration and corrosion of the electrical circuit. This was a contributing factor to hearing aid failure.

In the figure, reference numeral 1 denotes a hearing aid case having a substantially banana shape, and is composed of a case member 2 and a case member 3. Reference numeral 4 denotes a joint formed by joining the case member 2 and the case member 3. 5 is the volume,

によつて閉塞空間１１となつている。 As clearly shown in FIG. 3, the printed circuit board 10 is fitted into the notch 2A of the case member 2 and serves to secure one end thereof. At the same time, the notch 2A is formed into a closed space 11 by the case member 2, the case member 3, and the printed board 10.

飴状のシール材が好適である。 A sealing material is installed in this closed space 11. There are various sealing materials, and for example, an elastic material such as rubber may be used. Of course, if an elastic body is used as the sealing material, the case members 2 and 3 must be joined together and the printed board 10 must be fitted against the elastic force of the elastic body.
Therefore, the case members 2 and 3 must have a certain degree of strength, and the other end of the printed board 10 must be firmly fixed. Considering these points, a syrup-like sealing material such as liquid packing or silicone grille is suitable.

The present invention is not limited to this, and the point is that the closed space 11 may be formed by the case members 2 and 3 and the printed board 10. Therefore, for example, the fourth
As shown in the figure, notches 2A and 3A are formed on the joint end surfaces of both case members 2 and 3.
A, 3A may be fitted with printed boards 10 to form a closed space 11 after all. Note that a sealing material is interposed in the closed space 11.

As described above, in the present invention, a notch is provided in the case member, a printed board is fitted into the notch to form a closed space, and a sealing material is interposed in this closed space. Therefore, the present invention makes clever use of the printed circuit board already present in the hearing aid case, and forms an enclosed space without using special members. Moreover, it is also useful for fixing one end of the printed board. Furthermore, a sealing material is installed at the joints formed between the case members, thereby preventing water from entering through the joints.
