PROBLEM TO BE SOLVED: To provide a ground leakage breaker which is facilitated in assembling work of components and enabling a printed circuit board mounted with circuit components of an electric leakage detection circuit, etc., to be separated from a tripping plate without using dedicated members. SOLUTION: A printed circuit board housing recessed part 58 is provided in a bottom part of a body 1 for housing a printed circuit board 61 from above the bottom part of the body 1. Vertical walls 93 are integrally formed with both side parts of a bottom part of the body 1 in a boundary position between the printed circuit board housing recessed part 58 and a frame housing part 35, so that upper ends of the vertical walls 93 are situated at a level lower than the level of an upper end edge of a through-hole 63 in a zero-phase sequence current transformer ZCT by a size substantially equal to the diameter of braided wires 34, and a wall 94 higher than the vertical walls 93 is erected between the vertical walls 93, 93. The wall 94 forms a separation wall for laterally separating the braided two-pole wires 34 put through the through-hole 63 in the zero-phase sequence current transformer ZCT and guiding them to disposing positions of bimetallic strips 10 on laterally both side of the bottom part of the body 1.
