To provide an optical path bending connector and the like capable of suppressing damage of an optical fiber and reducing transmission loss as well.SOLUTION: In an optical path bending connector, an optical fiber 5 comes into contact with a first guide part 21a at an inner side of a bend. The first guide part 21a is disposed with a gap left from a portion of a fixing member 13 in which the optical fiber 5 is drawn. That is, a first noncontact part 25a in which the optical fiber 5 does not come into contact with a guide member 11 is provided between a part of the fixing member 13 in which the optical fiber 5 is drawn and the first guide part 21a. Furthermore, the optical fiber 5 comes into contact with a second guide part 21b at an outer side of the bend. The second guide part 21b is disposed with a gap left from the first guide part 21a, and a second noncontact part 25b in which the optical fiber 5 does not come into contact with the guide member 11 is also provided between the first guide part 21a and the second guide part 21b.SELECTED DRAWING: Figure 4 【課題】 光ファイバの破損を抑制するとともに、伝送ロスも低減することが可能な光路曲げコネクタ等を提供する。【解決手段】 光ファイバ５は、曲げの内側において、第１ガイド部２１ａで接触する。第１ガイド部２１ａは、固定部材１３の光ファイバ５が引き出される部位から離間して配置される。すなわち、固定部材１３の光ファイバ５の引き出し部と第１ガイド部２１ａとの間には、光ファイバ５がガイド部材１１と接触しない第１非接触部２５ａが設けられる。また、光ファイバ５は、曲げの外側において、第２ガイド部２１ｂと接触する。第２ガイド部２１ｂは、第１ガイド部２１ａから離間して配置され、第１ガイド部２１ａと第２ガイド部２１ｂとの間にも、光ファイバ５がガイド部材１１と接触しない第２非接触部２５ｂが設けられる。【選択図】図４
