PROBLEM TO BE SOLVED: To provide an optical switch which can be packaged at a high density. SOLUTION: A plurality of optical fibers are lined up in parallel at equal intervals and one lens is parted by the focal length of this lens from the end faces of a plurality of the optical fibers and is arranged by aligning the central lines of a plurality of the optical fibers and the central axis of the lens. A first mirror having a reflective surface perpendicular to the central axis of the lens and a second mirror having a reflective surface of the angle different from perpendicularity by half the difference in the angle formed by the optical axis of the light emitted from the optical fiber which is an input port with the central axis of the lens and the angle formed by the optical axis of the light to be coupled to the optical fiber which is an output port with the central axis of the lens are removably arranged at the focus on the side opposite to a plurality of the optical fibers of the lens.
