A switching power supply includes a switching circuit, a main transformer, a rectifier circuit, and an output smoothing circuit, which are mounted on a base plate. Voltage transformation of an inputted direct current voltage is performed through collaboration among the above. A pedestal portion is formed on the base plate, and a channel to cool down electronic parts such as a diode is formed inside the pedestal portion. Since the channel is thus formed inside the pedestal portion, the device will not be larger-sized even when the channel is formed. Moreover, at least any of a switching element and a diode is mounted on the pedestal portion, and a choke coil is mounted in a region other than a region where the pedestal portion is formed. Therefore, even with the pedestal portion, it is significantly suppressed for the device to be larger-sized.

Switching power supply

According to the present invention, there is provided an electronic components mounting structure constituted by a plurality of electronic components having lead terminals respectively, and conductors having connection portions to be connected to the lead terminals of the electronic components, in which the lead terminals of the electronic components are aligned with the connection portions of the conductors and the lead terminals and the connection portions are welded with each other.
