Abstract
A switching power supply has electronic parts that configure a switching circuit. The electronic parts are accommodated in a casing. A seat member is formed unitarily with the casing on which the electronic parts are mounted. A coolant channel is formed through the seat member so as to be open at least at two positions of an outer wall surface of the casing. Coolant that flows through the coolant channel cools the electronic parts mounted on the seat member.
