PROBLEM TO BE SOLVED: To provide a ground-fault interrupter in which a work for assembling components in an apparatus is easy. SOLUTION: There are provided a handle, a contact of a plurality of poles, a zero-phase current transformer ZCT which detects unbalanced currents between the poles, a circuit board 73 implemented with a ground-fault interrupter which outputs a leakage detection signal when the zero-phase current transformer ZCT detects unbalanced currents, a coil 68 which is connected to the circuit board 73 and is energized based on the leakage detection signal from the leakage detection circuit, a coil frame 69 around which the coil 68 is wound, and a leakage tip means which forcedly opens the contacts of a plurality of poles when the coil 68 is energized. The zero-phase current transformer ZCT is provided with a coil frame holding part 310 which, protruding outside from the end surface of the circuit board 77, moves the coil frame 69 from the circuit board 73 side toward the zero-phase current transformer side for engagement of the coil frame 69.
