Abstract
A coil device includes a core having a loop-shaped magnetic path and a first winding part. The first winding part is wound around the core so as to pass through an inner region of the core surrounded by the core. In the inner region of the core and an outer region of the core, a metal base substrate in which a coil pattern is formed with an insulating layer interposed on a metal base body is disposed. A cooling body is thermally bonded to a side of the metal base body opposite to a side where the insulating layer and the coil pattern are formed. The first winding part includes the coil pattern.
