PROBLEM TO BE SOLVED: To provide a circuit breaker with a display function with which a closed circuit state and an open circuit state can surely be recognized and neither display of closed circuit nor of open circuit can be seen in a trip state. SOLUTION: A slide plate 38 is set up between a flange part 23b of a handle rotating like a lever and a case 1. The knob part of the handle is fit into a hole of the slide plate 38, which is arranged so as to slide relatively with the knob part of the handle. It is so structured that a closed-circuit display label 40 is stuck on an open-circuit side surface of the flange part of the handle, and an open-circuit display label 39 is stuck on a lingual part of a closed-circuit side of the slide plate, so that the closed-circuit display label 40 overlaps with the closed-circuit side lingual part 38c of the slide plate 38 and the open-circuit display label 39 overlaps with the wall of a case 37, neither labels to be seen.
