ABSTRACT:
An optical fiber fixing member 11 including an optical fiber engaging portion 15 for positioning/engaging an optical fiber F. The optical fiber engaging portion 15 is provided with two inclined faces 12, for supporting a side wall of the optical fiber when the optical fiber F is engaged in the optical fiber engaging portion 15, and a bottom face 13 positioned between the inclined faces 12. The bottom face 13 is flat. Additionally, in a sectional face perpendicular to an optical axis of the optical fiber F supported by the inclined faces 12, in a boundary portion in which the bottom face 13 and the inclined faces 12 are connected, inclinations of the bottom face 13 and the inclined faces 12 are discontinuous. Therefore, when the optical fiber engaging portion 15 is observed while a light is radiated to the bottom face 13 from above or from below, the contrast between the bottom face 13 and the inclined face 12 by a reflected light or a transmitted light is enhanced.
