ゃ断器。In a circuit breaker comprising a conductor and a contact fixed to the conductor, and having a pair of movable and fixed electric contacts that open and close with each other, the conductor of the movable and fixed electric contact is connected to the center of the fixed part of the contact. Each is bent into an L-shape so that the axis is perpendicular to the surface of the contact, and the conductor of the movable electric contact is formed with a bent part that serves as a current path in the opposite direction to the fixed part of the contact. A circuit breaker characterized by:
