There are formed a plurality of intermittent connection portions in which a first connection portion that is formed from the common covering layer and a non-connection portion are alternately formed between the optical-fibers. There are formed a plurality of continuous connection portions in which a second connection portion that is formed from the common covering layer is continuously formed between optical-fibers. The intermittent connection portions include a central intermittent connection portion at a central portion of the optical-fiber ribbon in a width direction. The continuous connection portions include adjacent continuous connection portions. A thickness of adjacent continuous connection portion is larger than a thickness of the central intermittent connection portion and is larger than a thickness of the continuous connection portion other than the adjacent continuous connection portions.
