An oil filter includes a base, a cap mounted to the base to be detachable and forming a filter case in association with the base, a cylindrical filter element accommodated inside the filter case, and an inner cylinder disposed inside the filter element and attached to the cap. The cap has a head portion to which an engaging member is formed so as to extend inside the filter case, an axial one end of the inner cylinder is fitted to an outside of the engaging member to be detachable. The inner cylinder is provided with a stopper projecting in a radially outward direction thereof and having a tip end abutting against an inside surface of the filter case to thereby prevent the inner cylinder from falling down, and the stopper is disposed between the head portion of the cap and the filter element.
