    摘要： Provided is a circuit breaker capable of minimizing a change in the structure of, for example, a case even when a material (thermal conductivity) forming a stud is changed.
    A stud 20 includes a base portion 21 that is provided in a case 2 and a protruding portion 22 that protrudes from the case 2. The cross-sectional area of the protruding portion 22 is more than that of the base portion 21. When the cross-sectional area of the protruding portion 22 is more than that of the base portion 21 in the stud 20, the thermal conductivity of the protruding portion 22 increases and it is possible to increase the thermal conductivity from the protruding portion 22 to an external conductor connected to the stud. In addition, since the surface area of the protruding portion 22 increases, the amount of heat dissipated from the protruding portion 22 increases. In this case, since the dimensions of the base portion 21 inserted into a stud insertion hole 2b of the case 2 do not vary, it is not necessary to change the dimensions of the insertion hole 2b of the case 2. Therefore, it is possible to minimize a change in the structure of a component even when the material forming the stud is changed.
