Abstract: A circuit breaker can minimize a change in a structure of a case when a material forming a stud is changed. A stud includes a base portion provided in the case and a protruding portion protruding from the case. A cross-sectional area of the protruding portion is more than that of the base portion; thereby a thermal conductivity of the protruding portion increases and the thermal conductivity from the protruding portion to an external conductor connected to the stud increases. In addition, since a surface area of the protruding portion increases, an amount of heat dissipated from the protruding portion increases. In the invention, since dimensions of the base portion inserted into a stud insertion hole of the case are not changed, it is not necessary to change the dimensions of the insertion hole of the case.
