[Problem] To suppress breakage of a connection part when an optical fiber ribbon is bent in a width direction.
[Solution] An intermittent connection-type optical fiber ribbon of the present disclosure includes: a plurality of optical fibers aligned in a width direction. Separation parts that separate the optical fibers adjacent to each other are intermittently formed in a length direction, to form a connection part between the separation part and another separation part of the separation parts aligned in the length direction. Air bubbles are contained in the connection part.
