A device for bending an optical fiber and receiving light is provided with a recessed holding member having a recess, a projecting holding member having a projection projecting toward the recess, light receiving elements for receiving leak light from an optical fiber held between the recess and the projection, and a supplemental support mechanism that is substantially independent of the recess or the projection and supplementarily supports the optical fiber between the recess and the projection such that the leak light from the optical fiber is received by center of the light receiving elements.
