<p>An optical transmission medium bend working device that reduces bending loss of an optical transmission medium includes: an arc-discharge electrode (133) that partially and sequentially heats a bend working area (A) of a tape core wire (F) in an up-down direction, the tape core wire extending in the up-down direction with a distal end thereof being located on a lower side, the bend working area being located above the distal end; a core wire holding unit (123) that holds a portion of the tape core wire (F) located above the bend working area (A); and a bending arm (143) that applies force to the tape core wire (F) in a state where the bend working area (A) is heated to bend the tape core wire (F) at the bend working area (A).</p> |
