There is provided an interchangeable lens type camera which is so safe as to prevent spread of fire when dust strays into the interior of the camera to cause heating and/or electrical leakage of the electric circuitry and invite ignition. The camera includes a case having a mount section for mounting a detachable lens; electric circuitry provided within the case; and a member covering at least a portion of the electric circuitry to prevent the electric circuitry from being exposed to the exterior when the lens is detached from the mount section.
