摘要： For an enhanced coupling efficiency between a light source and an optical fiber bundle: the optical fiber bundle is made up by a dense bundle of optical fibers, with an integrated portion composed of fusion-integrated distal ends of the bundled optical fibers, and the integrated portion has, in a longitudinal sectional plane along a center axis of the optical fiber bundle, a lateral side thereof formed, in a shape of arc radially outwardly convex with respect to a straight line interconnecting an end point at a front end face side of the integrated portion and an end point at a rear end side thereof, to locate at a radially inner side with respect to an extension toward the integrated portion of a line constituting an outline of a portion else than the integrated portion of the optical fiber bundle.
