A communication device which efficiently dissipates locally generated heat, and at the same time is small in size and light in weight, is provided. A high-efficiency heat-dissipating fin section having fins disposed on an heat pipe which is bent into an S shape is mounted on a high-temperature heat-generating section that generates high-temperature heat. A heat-dissipating fin section having fins disposed on a heat-receiving plate thereof is mounted on a low-temperature heat-generating section that generates heat having a lower temperature than that of the high-temperature heat generated by the high-temperature heat-generating section. This makes it possible to efficiently dissipate heat and reduce the size and weight of the communication device.
