PROBLEM TO BE SOLVED: To provide a terminal structure of a circuit breaker capable of providing a connection display mechanism for individual quick connection terminals even in the circuit breaker structured to vertically arrange the quick connection terminals. SOLUTION: The connection display mechanism 7 comprises a sliding member 16 juxtaposed to the quick connection terminal 11 and longitudinally moving in a wire inserting direction, a display member 17 arranged near a terminal port 3a and turned by the longitudinal movement of the sliding member 16 by the engagement of a base part of the sliding member 16 with the display member 17, and a coil spring 18 energizing the sliding member 16 toward the terminal port 3a. A breaker case 1 adjoining the terminal port 3a is provided with a confirmation window 6 making the display member 17 visible. The sliding member 16 has a contact piece 16a contacted by the tip of a wire 10 inserted in the quick connection terminal 11, and is moved toward the inside of a terminal by the contact of the wire 10 to turn the display member 17.
