To provide an optical apparatus attachment method by which imaging quality can be improved without increasing a manufacturing cost.
In the optical apparatus attachment method, an optical apparatus 520 is attached to a cabinet 10 for attaching optical parts where a projection lens 600 are attached in advance, in order to assemble a projector which is equipped with: the optical apparatus 520 for compositing an image formed by respectively modulating a plurality of color rays; the projection lens 600 for projecting the image composited by the optical apparatus 520; and the cabinet 10 for attaching optical parts to which the optical apparatus 520 and the projection lens 600 are attached. The optical apparatus attachment method includes a position adjustment step in which, after the optical apparatus 520 is held on the attaching surface of the cabinet 10 for attaching optical parts, the optical apparatus 520 is adjusted in its position by being turned in the mounting surface of the cabinet 10 for mounting the optical parts.
