Abstract
An on-board mounting electronic apparatus including an apparatus body 6, made up of a main board 4 and terminal pins 5 for connection with a circuit board 21. The terminal pins 5 extend from an underside of the main board 4. A heat dissipation plate 8 is arranged on an upper surface of heat generating components 2 mounted on the main board 4. The heat dissipation plate 8 is thermally connected with the surface of the heat generating components 2. Such structure may be applied to an on-board mounting electric power supply as well.
