A composite profile evaluating method includes an adjusting step and a composite profile detecting step. In the adjusting step, a relative position between a fixed cam and a movable cam is adjusted. In the composite profile detecting step, at least either one of a first contact element, which is displaced along a diametrical direction of the fixed cam upon contacting a cam surface of the fixed cam, and a second contact element, which is displaced integrally with the first contact element and along a diametrical direction of the movable cam upon contacting a cam surface of the movable cam, is brought into contact with the cam surface of the fixed cam or the movable cam. In such a state, the composite profile is obtained by rotating the fixed cam and the movable cam, and detecting the amounts of displacement of the first and second contact elements.
