PROBLEM TO BE SOLVED: To enable the coupling structure of an optical fiber ribbon, in which adjacent optical fiber ribbons are intermittently coupled together in the longitudinal direction, to be reliably inspected.SOLUTION: An optical fiber ribbon inspection device according to the invention inspects the state of a notch in an intermittently notched optical fiber ribbon 1 in which a plurality of optical fiber ribbons are arranged in parallel in one row and integrated by common sheathing and intermittent notches are formed in the longitudinal direction between the adjacent optical fiber ribbons. The inspection device comprises: a roller 20 with protrusion having a protruding part for pressing into the notches in the intermittently notched optical fiber ribbons to expand the notches; a sensor (an optical sensor 30) for detecting the state of the surface of the roller 20 with protrusion; and a determination unit 31 for determining, on the basis of the result of detection by the sensor, that the intermittent notches are formed properly. 【課題】隣り合う光ファイバ心線間が長手方向に間欠的に連結された光ファイバテープ心線の連結構造を確実に検査できるようにする。【解決手段】光ファイバテープ心線の検査装置は、複数本の光ファイバ心線が平行一列に並べられて共通被覆により一体化され、隣り合う光ファイバ心線間の長手方向に間欠的な切込みが形成された間欠切込み光ファイバテープ心線１の切込みの状態を検査する。検査装置は、間欠的な切込みが掲載された光ファイテープ心線の切込みに圧入して切込みを拡げる突起部を有する突起付きローラ２０と、突起付きローラ２０の表面の状態を検出するセンサ（光学センサ３０）と、そのセンサによる検出結果に基づいて間欠的な切込みが適正に形成されていることを判断する判断部３１と、を備える。【選択図】図２
