PROBLEM TO BE SOLVED: To provide an electric leakage safety device capable of visually confirming breakage of a lightning arrestor element with sureness and replacing it simply and quickly. SOLUTION: A see-through part A made of a transparent or semitransparent material is arranged in free opening/closing at a part of a main body case 21, and a lightning arrestor 30 is arranged at the inside of the see-through part A so as to be observed from outside and to be freely attached and detached by opening of the see-through part A. The see-through part A is formed by a see-through case 25 made of resin opened toward the main body case side, and is jointed to the main body case 21 in free attachment/detachment. The arrestor 30 is mounted on a small base plate 31, and the small base plate 31 is jointed to a terminal stand 29 arranged at an outer surface of the main body case by a terminal screw 33.
