Abstract
Provided is a power supply device that can suitably release heat with a small number of parts. In an AC-DC converter that is a power supply device according to an embodiment of the present invention, a heat conductive member thermally connected to a base plate is thermally connected to an upper surface of a stacked coil board including a main circuit board and circuit boards. This configuration causes heat generated in the stacked coil board to be transferred to the base plate also from the upper surface of the stacked coil board via the heat conducting member, whereby the heat release effect can be increased. In addition, since the heat conducting member is the only member used for releasing heat, the heat release effect can be increased while the number of parts is kept from increasing.
