Abstract

An optical fiber ribbon includes a first multicore fiber having a plurality of first cores, a second multicore fiber arranged in parallel with the first multicore fiber, and a coating member. The coating member includes a first coating portion covering the first multicore fiber and a second coating portion covering the second multicore fiber. A first light-irradiated surface having a width larger than the diameter of the first core is provided in at least one region where a virtual line passing through at least two or more of first cores among the plurality of first cores or a virtual line passing through the center of the first multicore fiber intersects with the outer circumference of the first coating portion. The first light-irradiated surface includes a curved surface having a radius of curvature of 0.5 mm or more or a flat surface.
