To provide an earth leakage detection unit and an earth leakage breaker that make processing of conductor members easy, enable miniaturization of a device, and, in particular, excel in assemblability. Load side conductors (11T to 11N) and power supply side conductors (12T to 12N) are arranged on the one side and the other side in the axial direction of a zero-phase current transformer (8), respectively, so that through conductor portions (14S, 14N) and through conductor portions (13N, 13R) each of which are continuously fixed penetrate an annular core (9) from the one side and the other side in the axial direction of the zero-phase current transformer (8), respectively. With this configuration, the through conductor portions (13T, 13R, 14S, 14N) are jointed to joining portions (16T, 16R, 15S, 15N), and the power supply side conductors (12T to 12N) and the load side conductors (11T to 11N) are connected for each phase. Insulating coating portions (18S, 18N, 17R) are formed at least on the outsides of portions of the through conductor portions continuously fixed to the load side conductors and the power supply side conductor. |
