A small reflection mirror type optical fiber switch solves a problem of an inconsistent angle of a shutter operating position in a conventional reflection mirror type optical fiber switch. A reflection mirror type 2.times.2 optical fiber switch includes a first collimator lens assembly C1 having a pair of optical fibers disposed symmetrically with respect to an optical axis of a lens, and a second collimator lens assembly C2 having a pair of optical fibers also disposed symmetrically with respect to an optical axis of a lens. In an aligning block B, the first and second collimator lens assemblies are opposed and supported, with their optical axes aligned. A driving means MO moves a mirror of a reflection mirror assembly between a position where light is reflected and a position where light is transmitted.
