Summary:To provide a multi-core fiber having a connector, capable of preventing or relaxing a positional deviation caused on the end surface of a core when polishing the end surface of the multi-core fiber having at least one core spirally formed in a plurality of cores.SOLUTION: A multi-core fiber 1 having a connector includes: a multi-core fiber 10 having at least one core spirally formed in a plurality of cores; and a connector 20 provided in the end part of the multi-core fiber 10. The end part of the multi-core fiber 10 is served as a non-spiral part SP1 having a linear core (or a slack spiral part having a spiral frequency per unit length of the core less than that of a portion except the end of the multi-core fiber).SELECTED DRAWING: Figure 1 【課題】複数のコアのうちの少なくとも１つのコアが螺旋状に形成されているマルチコアファイバを端面研磨した場合に生ずるコアの端面における位置ずれを防止又は緩和することができるコネクタ付きマルチコアファイバを提供する。【解決手段】コネクタ付きマルチコアファイバ１は、複数のコアのうちの少なくとも１つのコアが螺旋状に形成されているマルチコアファイバ１０と、マルチコアファイバ１０の端部に設けられたコネクタ２０と、を備え、マルチコアファイバ１０の端部は、コアが直線状にされた非螺旋部ＳＰ１（又は、コアの単位長さ当たりの螺旋回数がマルチコアファイバの端部以外の部分よりも少なくされた緩螺旋部）とされている。【選択図】図１
