Housing body and electrical equipment

The present invention provides a housing body and electrical equipment. In the housing body in which a heat generator is housed, a reduction in costs of the housing body is desired, and the size of the housing body should be limited. The housing body comprises a first housing, inside which a first heat generator is housed, a heat sink for radiating heat generated by the first heat generator is arranged in a first zone of an outer surface; and a second housing in which a second heat generator is housed and which is fixed on a second zone different from the first zone of the outer surface. The thermal conductivity of the first housing may be lower than the thermal conductivity of the second housing.
