To provide a circuit breaker which enables a current sensor to be detachably fixed and held with a simple operation and eliminates a need of enlarging the circuit breaker for a current sensor attachment space when the current sensor is installed in the circuit breaker.
A current sensor fixing part which holds a current sensor is disposed at a connection terminal part formed at an end part of a power distribution apparatus. The current sensor fixing part includes a cylindrical part where a cable way, which is formed by connecting wiring connected with the exterior with the connection terminal part, penetrates therethrough. The current sensor fixing part holds the current sensor where a pair of arm parts protrudes from one end of a substrate, the inner side of the pair of arm parts is formed into a wiring insertion part where an end part is open, and magnetic detection elements are respectively disposed at the pair of arm parts.
