According to one embodiment, a DC-DC converter includes a mounting substrate and a semiconductor device. The semiconductor device includes a first switch element, a second switch element, a first interconnect layer receiving an input potential, a second interconnect layer connected with an inductor, a third interconnect layer receiving a reference potential, and a fourth interconnect layer connected with the inductor. These layers are disposed side by side in one direction on one layer. The mounting substrate includes a fifth interconnect pattern receiving an input potential and disposed adjacently on one side of a mounting region of the semiconductor device, a sixth interconnect pattern receiving a reference voltage and disposed adjacently on the one side of the mounting region, and a seventh interconnect pattern disposed adjacently on one other side opposite to the one side of the mounting region.
