Abstract
An electronic device having a heat generating part in an internal space between a front case and a rear case wherein the rear case is integrally molded with a metal sheet and the metal sheet is given relief shapes which increase its surface area, whereby the heat of the heating generating part is dissipated from the rear case and conduction to the front case is reduced. The relief shapes can be formed from a wave shape. The rear case may be made a bathtub shape. Relief shapes of the metal sheet may be exposed at the inside space of the electronic device at the side wall part of the rear case or its vicinity. As a result, the heat which is generated inside the housing of a small electronic device can be efficiently dissipated from the back side and conduction of heat to the front side can be made difficult.
