Note that 6 indicates a mounting part. Next, an example of the manufacturing method will be explained using FIG. 2. To manufacture this reflecting mirror 1, as shown in FIG. 2A, a frame T which is slightly larger than the shape of the reflecting mirror 1 is made
Spread metal foil, for example aluminum foil 2, over the entire surface of the
In this state, the frame T is pressed against a male mold 8 having a convex surface with the same curvature as the curve of the reflecting surface of the reflecting mirror 1.

上述せる本発明によれば、軽量で安価な反射鏡を得るこ
とが出来る。Next, as shown in FIG. 2B, adhesive is applied to the back surface of the aluminum foil 2 that is not pressed against the male die 8, and this back surface is covered with a mold 9, and the back surface and the mold 9 are formed. After placing expanded polystyrene pellets in the space to be heated to 150℃
The pellets are foamed by heating the pellets to
As shown in FIG. A reflecting mirror 1 is formed by covering the back surface of aluminum foil 2 with foamed polystyrene 3 as shown in C. Thereafter, a resin coating 4 was applied to the surface of the foamed polystyrene of the reflector 1 thus obtained,
By attaching rubber 5 to the corner portions, the reflecting mirror shown in FIG. 1 is obtained. [3- According to the present invention described above, a lightweight and inexpensive reflecting mirror can be obtained.
更に本発明は実施例に拘束されることなく音響の反射装
