A digital camera contains a circuit board and a battery box inside a housing. The housing and the battery box are made of plastic. The housing is fixed to the battery box with a tapping screw. A conductive plate for preventing the tapping screw from being charged is arranged between the housing and the battery box. Projections of the conductive plate penetrate into thread grooves of the tapping screw. The conductive plate transmits static electricity of the tapping screw to a grounding member of the circuit board.
