Abstract
An IC is mounted on a printed board. A radiator made of copper is arranged on the printed board so as to surround the IC and is fastened onto the printed board by screws provided on the back surface of the board. The central portion of a ceiling on the inner surface of the radiator protrudes downward and the lower surface of the protrusion becomes a contact surface contacting with the IC. Heat-conducting rubber is also provided on the lower portions of the radiator, i.e., portions at which the radiator contacts with the printed board. With this arrangement, a heat radiating member for the heat generating device having high radiation effect can be obtained.
