PROBLEM TO BE SOLVED: To provide an electric equipment capable of insulating a terminal base with a power supply line of a commercial power supply connected from other circuit components in simple structure. SOLUTION: A case of an interphone device comprises an approximately box shaped base 2 with its front face opened, and a cover attached covering to the front face of the base 2. The ternminal base 60 with the power supply line connected to it, and a main circuit board 11 with a power supply block for converting the power voltage of the commercial power supply supplied through the terminal base 60 to an operating voltage of the electrical circuit and circuit components of the electrical circuit packaged are housed. The terminal base 60 is packaged on a face of the main circuit board 11 opposite to the base 2, slits 11c and 11d passing through the main circuit board 11 in its thickness direction are formed on a periphery of the packged part of the terminal base 60, and insulating walls 22a and 22b are inserted into the slits 11c and 11d from the bottom wall of the base 2 to project to the opposite side of the main circuit board 11.
