A crankshaft includes a first oil hole, a second oil hole, and a through hole. The second oil hole extends in a direction in which the second oil hole intersects the first oil hole. A first extension is an imaginary line extending from an inner wall surface of the first oil hole on a second oil hole side. A second extension is an imaginary line extending from an inner wall surface of the second oil hole on a first oil hole side. The through hole passes through an intersection between the first extension and the second extension. At least one end of the through hole opens on an outer peripheral surface.
