Abstract
The electronic circuit device includes: a first wiring pattern which is formed on a first main surface of a circuit board, has circuit elements including a switching element and mounted along a predetermined direction, and includes a virtual shortest current path connecting the circuit elements to each other along the predetermined direction; a second wiring pattern which is formed on a second main surface, and includes an opposing current path that opposes an area where the virtual shortest current path is formed; vias electrically connecting the first and second wiring patterns; and vias for heat transfer, connecting a mount area for the switching elements on the first main surface with an area on a side of the opposing current path on the second main surface. The heat dissipation member is in contact with the second main surface.
