Provided is a manufacturing method of an optical fiber ribbon for manufacturing an intermittent-connection-type optical fiber ribbon including a connection part and a non-connection part. The manufacturing method includes: a release agent applying process of intermittently applying a release agent for preventing optical fibers from being bonded to each other with a connection resin in a longitudinal direction of the optical fibers in a state where the optical fibers are arranged in parallel; and a connection resin applying process of allowing the optical fibers in the state of being arranged in parallel to pass through a die for applying the connection resin around the optical fibers after the release agent applying process, and of curing the connection resin.
