PROBLEM TO BE SOLVED: To provide a ground fault interrupter in which an insulating member can be simply installed on a conductive plate penetrating through the zero-phase current transformer. SOLUTION: The insulating member 6 is formed so as to have a U-shaped cross section by a base part 6a formed so as to extend along U-shaped part 5 of an R-phase conduction plate 2R and a T-phase conduction plate 2T, and an overhanging part 6b protruding toward inside of the U-shape part 5 at the both top and bottom ends of the base part 6a. The insulating members 6 are covered on the R-phase conductive plate 2R and the T-phase conductive plate 2T respectively and is penetrated through a through hole 1a of the zero-phase current transformer, and then, an S-phase conductive plate 2S is interposed between the R-phase conductive plate 2R and the T-phase conductive plate 2T, and is penetrated through the through hole 1a of the zero-phase current transformer 1, thereby, the insulating member 6 is prevented from falling off by interfering with the S-phase conductive plate 2S.
