A drive circuit drives a plurality of switching elements connected in parallel to each other. The drive circuit includes an operating unit that performs first and second switching processes. In the first switching process, under a condition that a first current detection value acquired before next time an on-command is received is determined to fall below a first threshold that is equal to or less than a threshold current, an on-operation target that is used the next time the on-command is received is set to a second switching element. In the second switching process, under a condition that the second current detection value acquired before the next time the on-command is received is determined to exceed a second threshold that is equal to or greater than the threshold current, the on-operation target that is used the next time the on-command is received is set to a first switching element.
