A power module, including a high-side switching element and a low-side switching element connected to form a half bridge circuit, a high-side drive circuit which drives the high-side switching element, a low-side drive circuit which drives the low-side switching element, and a high-side current detection circuit which detects a current of the high-side switching element. The high-side drive circuit includes a high-side variable delay circuit which adjusts, according to a value detected by the high-side current detection circuit, a length of a high-side delay time from a time when a signal is inputted to the high-side drive circuit to a time when the high-side switching element is driven.
