Provided is an optical fiber ribbon capable of achieving higher density and reduction in diameter and accurately placing optical fibers in V-shape grooves in a fusion machine without failure. The optical fiber ribbon 1 includes three or more of optical fibers 2 arranged in parallel and connecting portions 3 each connecting adjacent two optical fibers 2 together, the connecting portions 3 being intermittently provided in each of a ribbon longitudinal direction and a ribbon width direction. The optical fiber ribbon 1 has an outer diameter dimension of the optical fibers 2 which is set to smaller than or equal to 220 mu m, and has a distance between the centers of the adjacent two optical fibers which is set to 250+-30 mu m. 本发明的目的在于提供种能够实现高密度细径化且能够不脱落地在熔接机的V字槽载置光纤的光纤带芯线。种光纤带芯线(1)，将3芯以上的光纤(2)并列配置并利用连结部(3)将彼此相邻的2芯的光纤(2)之间连结，将该连结部(3)沿着带芯线长度方向及带芯线宽度方向分别间断地设置。在该光纤带芯线(1)中，光纤(2)的外径尺寸设为220μm以下，且相邻的光纤(2)的中心间距离L设为250±30μm。
