PROBLEM TO BE SOLVED: To allow a connection point of an optical fiber in a lengthwise direction to be positioned with relatively high accuracy in a mechanical splice.SOLUTION: A first projecting part 3a is provided on a first slope 3c and has a first end surface 3a2 and extends from a first region R1 along a bottom part 3e to reach a first boundary surface Sf23 between a second region R2 and a third region R3, and a second projecting part 3b is provided on a second slope 3d and has a second end surface 3b2 and extends from the third region R3 along the bottom part 3e to reach a second boundary surface Sf12 between the first region R1 and the second region R2. When an optical fiber F1 is inserted from the first region and an optical fiber F2 is inserted from the third region, the optical fiber F1 butts against the second end surface 3b2 of the second projecting part 3b and the optical fiber F2 butts against the first end surface 3a2 of the first projecting part 3a. 【課題】メカニカルスプライスにおいて、長手方向における光ファイバの接続点の位置決めが比較的に高い精度で行えるようにする。【解決手段】第１突出部３ａは、第１斜面３ｃの上に設けられており、第１端面３ａ２を備えており、第１領域Ｒ１から底部３ｅに沿って第２領域Ｒ２と第３領域Ｒ３との第１境界面Ｓｆ２３に至るまで延びており、第２突出部３ｂは、第２斜面３ｄの上に設けられており、第２端面３ｂ２を備えており、第３領域Ｒ３から底部３ｅに沿って第１領域Ｒ１と第２領域Ｒ２との第２境界面Ｓｆ１２に至るまで延びている。第１領域から光ファイバＦ１が挿入され、第３領域から光ファイバＦ２が挿入されると、光ファイバＦ１は、第２突出部３ｂの第２端面３ｂ２に突き当たり、光ファイバＦ２は、第１突出部３ａの第１端面３ａ２に突き当たる。【選択図】図１
