This internal combustion engine includes a piston, an oil jet that operates at a predetermined operating pressure to supply oil to the piston, and a hydraulic controller provided upstream of an oil passage including the oil jet. The hydraulic controller includes a constantly opened first passage through which the oil having a pressure lower than the predetermined operating pressure is supplied to the oil jet, a second passage provided alongside of the first passage and being openable and closable, through which the oil having a pressure higher than the predetermined operating pressure is supplied to the oil jet in combination with the first passage in a state where the same is opened, and an opening-closing control portion that controls the second passage to be in an open state when actuating the oil jet, and controls the second passage to be in a closed state when stopping actuating the oil jet.
