Abstract:
The purpose of the present invention is to provide: a cooling structure with which it is possible to maintain an appropriate positional relationship between a cooling pipe and a heat-generating body and to provide sufficient cooling even when the size of the heat-generating body is similar to or smaller than the cooling pipe; a power amplifier; and a transmitter. Accordingly, the cooling structure of the present invention is provided with: a cooling pipe which includes a base material having formed a refrigerant flow passageway, and a first layer formed on an outer surface of the base material; and a cold plate with the cooling pipe cast therein.
