A circuit breaker is provided to improve functionality of a load side terminal by arranging a terminal inlet of a load side terminal, a window for confirming a contact, and an insertion groove for checking measurement on a front of a breaker case into top and bottom. An control lever(3) is installed on a top surface of a breaker case(2) of a thin box type, and opens/closes an electric circuit. Three load side terminals(4) and three power side terminals(5) are arranged on a front and a rear of the breaker case. A terminal inlet(7) is installed on a front of the breaker case, and connects a wire(9) to an electrode of the load side terminal. The electrode is installed in an inner side of the terminal inlet. A wire of a load wiring is inserted in the terminal inlet, and connected to a grip part of the electrode. A confirming window(11) for confirming a connection state of the wire is formed on a top side of the terminal inlet. An insertion groove(12) is installed in a bottom side of the terminal inlet, and connects a measurement terminal of a meter to the electrode.
