1. A power module comprising:
a power semiconductor device and a non-power semiconductor device configuring a power supply circuit to perform power conversion;
a resin substrate, both the power semiconductor device and the non-power semiconductor device being mounted on the resin substrate; and
a cooling device being configured to cool the power semiconductor device, the cooling device including a cooling fluid passage disposed on a side opposite a mounting surface of the resin substrate, the power semiconductor device and the non-power semiconductor device being mounted on the mounting surface of the resin substrate, the cooling fluid passage allowing a cooling fluid to cool the power semiconductor device to pass therethrough,
a shortest distance between the power semiconductor device and the cooling fluid passage being shorter than a shortest distance between the non-power semiconductor device and the cooling fluid passage.
