Abstract
An electronic component provided with a heat radiative ceramic plate that is protected from cracks. Such a heat radiative electronic component is composed of an electronic device, such as a semiconductor device with an integrated circuit built therein, having a heat radiative plate bonded on its upper surface. The heat radiative plate is formed by a ceramic plate coated with a resin layer. The ceramic plate is a 1 mm to 2 mm thick quadrangular plate prepared by sintering cordierite powder, which has a high emissivity of far-infrared rays. The resin layer entirely or partly covers the surface of the ceramic plate, thereby preventing the plate from breaking and/or chipping and scattering ceramic powder to the surrounding area.
