Abstract
An optical fiber holder includes a holder main body, a V-groove which is formed on an upper surface of the holder main body and accommodates a first optical fiber, a recessed groove which is formed on a same straight line with the V-groove and accommodates a second optical fiber having a coating portion with a larger outer diameter than the first optical fiber, and an abutting portion which is provided on an end portion of the recessed groove on an opposite side to the V-groove and includes an opening portion which has a smaller width than the recessed groove. When the second optical fiber is accommodated in the recessed groove, a fiber core wire of the second optical fiber protrudes to an outside via the opening portion and an end portion of the coating portion of the second optical fiber abuts on the abutting portion.
