2. Description of the Related Art Conventionally, an electronic image pickup apparatus such as a camera for taking a photograph using a silver halide film or the like, and a digital camera for electronically recording an image picked up by an image pickup device or the like, has a main body. Is generally manufactured by injection molding or the like using a non-conductive material. Further, among such cameras and electronic imaging devices, those having a strobe device in a main body have been widely used.

When a strobe device is arranged in a main body of a camera, an electronic image pickup device or the like, if the case is formed of a non-conductive member, the strobe device is disposed inside the case. There was no need to particularly consider the distance between the housing member and the inner wall surface.

By minimizing the size of the camera by arranging them close to each other.

However, in an electronic image pickup apparatus and the like, since a large number of electronic circuits for performing high-speed processing are provided inside the main body, the electronic circuit in the main body is compared with a camera or the like using a conventional silver halide film. The electromagnetic wave noise generated from the above is large. This electromagnetic wave noise or the like causes deterioration of image quality in the above-described electronic imaging apparatus that electronically records an image, and needs to be removed.

Therefore, in the above electronic imaging apparatus, the casing, which is the structure of the main body, or the outer surface thereof is formed of a conductive material using, for example, plating, painting, metal fiber-containing resin, or the like. Means for preventing such electromagnetic wave noise and the like have been put to practical use. Further, for the purpose of designing the apparatus main body, the above-described plating, painting, metal fiber-containing resin, and the like are generally used for the housing member.

In the case where the device is miniaturized by arranging the devices close to each other, a discharge (spark) occurs between the strobe reflector and the conductive housing member of the strobe device. Could be done.

In this case, if a discharge occurs and the current leaks to the main body, there is a danger that control means such as a CPU for controlling the entire apparatus will be destroyed. Therefore, it is important to reliably prevent the above-described discharge from occurring.
