To provide the heat radiative mechanism of a shutter for an electromotive camera, which is so arranged as to ideally radiate the heat generated by a motor for driving the vane of a shutter.

A motor for driving the vane of a shutter and a flexible printed wiring board 13 are attached to a shutter's base plate 7a made of synthetic resin. Moreover, the motor has a stator frame 10 made of synthetic resin bearing a rotor, a coil 11 wound thereon, and a cylindrical yoke 12 surrounding them. On the other hand, for the flexible printed wiring board 13, a copper foil pattern for power supply to the coil 11 is made between band parts 13a and 13c, and a copper foil pattern for heat conductivity is made between the band parts 13a and 13c. Then, for the copper foil pattern for heat conductivity, its one end is in contact with the yoke 12, and its other end is in contact with a metallic member on the side of the camera main body. Accordingly, the heat generated in the coil 11 is radiated ideally.
