<P>PROBLEM TO BE SOLVED: To provide a compact, strong electrostatic discharge protective component that is superior in heat radiation property, and to provide a light-emitting diode module that uses the electrostatic discharge protection component. <P>SOLUTION: The electrostatic discharge protective component comprises a ceramic sintered body, having a ceramic substrate 12, a varistor portion 10 formed thereon, and a glass ceramic layer 14 formed further thereon; a pair of terminal electrodes 13a, 13b provided on the surface of the ceramic sintered body; a pair of external electrodes provided on a surface at a side opposite to terminal electrodes 13a, 13b; and a heat-conducting portion 15 penetrating through the ceramic sintered body vertically. In the light-emitting diode module, the light-emitting diode element is mounted and packaged at the heat-conducting portion 15 of the electrostatic discharge protection component. By providing the heat-conducting portion 15, heat generated from the mounted component can be released efficiently in the electrostatic discharge protection component and the light-emitting diode module. <P>COPYRIGHT: (C)2009,JPO&INPIT |
