An optical fiber holder comprising a pair of hollow metal members opposingly provided so as to interpose an optical fiber between them, and a holding case that holds the hollow metal members in such a state that their peripheries are pressed against its inner wall. The hollow metal members are in the shape of half-round cylinders on the whole, and are provided in such a manner that the planar portions thereof face each other so that the optical fiber is held between the hollow members at the center of each planar portion thereof. The optical fiber can be elastically fixed without causing a damage to the optical fiber main body and can be firmly fixed because of the great contact areas assured in the axial direction and in the peripheral direction.
