<P>PROBLEM TO BE SOLVED: To provide an electronic controller which can be made compact and in which heat dissipation is enhanced. <P>SOLUTION: The electronic controller includes a circuit board 2 having a wiring pattern, and at least a pair of heat-generating electronic components 5A, 5B out of a plurality of heat-generating electronic components mounted on the circuit board 2 contiguously to each other. The heat-generating electronic components 5A, 5B are constituted by extending a lead 9 for electrical and mechanical connection with the circuit board 2 to one side, and extending a metal plate 10 for heat dissipation to the other side. The pair of heat-generating electronic components 5A, 5B mounted contiguously to each other are arranged so that the lead 9 and the metal plate 10 for heat dissipation are directed in a direction intersecting the adjoining direction, and the directions of the lead 9 and the metal plate 10 are reversed from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
