Summary:PROBLEM TO BE SOLVED: To provide an optical cable capable of, after removal of a sheath, saving such time and labor as cutting a roughly wound string by using a cutter etc.SOLUTION: In an optical cable 10, a cable core 14 has: units 11a each formed such that multiple coated optical fibers are tied in a bundle; and roughly wound strings 13 wound around the units, and an outside of the cable core is covered with a sheath 15. The roughly wound strings are formed of a material whose breaking strength declines due to heat in extrusion-molding the sheath. Then, the cable core may further have a fibrous interposition 12 disposed around the units. 【課題】外被の除去後に刃物等を用いて粗巻き紐を切断するような手間を省略できる光ケーブルを提供する。【解決手段】光ファイバ心線を複数本束ねたユニット１１ａと、ユニットの周囲に巻き付けた粗巻き紐１３とを有するケーブルコア１４の外側を外被１５で被覆した光ケーブル１０である。粗巻き紐は、外被の押出成形時の熱により破断強度が低下する材料で形成されている。なお、ケーブルコアは、ユニットの周囲に配された繊維状の介在１２をさらに有してもよい。【選択図】図１
