Abstract
An optical path deflecting prism for endoscope which is used for observing an object in an oblique direction, includes a first prism and a second prism, and the first prism and the second prism are cemented. The first prism has a first polished surface and a second polished surface. The first reflecting surface is a mirror surface having a mirror coating applied to a polished surface of a flat plate, and is fixed by gluing to the fifth polished surface of the second prism upon adjusting an angle so as to correct an optical-axis shift which occurs due to a manufacturing error of the first prism and the second prism.
