A method for manufacturing an intermittently connected optical fiber ribbon that includes a plurality of optical fibers arranged side by side, and connection parts arranged intermittently and each connecting two adjacent ones of said optical fibers, said method comprising: a step of applying, between said optical fibers, a liquid-form UV-curable resin composition including a siloxane structure in its molecule; and characterized by a step of removing a portion of said liquid-form UV-curable resin composition applied between said optical fibers while leaving a portion of said liquid-form UV-curable resin composition, wherein said removing is performed by rotary blades each having a recess, the rotary blades rotate in accordance with a supply speed of the optical fibers, and the rotary blades remove said liquid-form UV-curable resin composition applied between the optical fibers while leaving said liquid-form UV-curable resin composition at the recess; and a step of irradiating said liquid-form UV-curable resin composition between said optical fibers with UV rays and forming said connection parts, wherein: said including a siloxane structure in its molecule refers to a state wherein silicone is incorporated in a resin by cross-linking; said UV-curable resin composition includes, in a UV-curable resin serving as a base agent, from 0.1 wt% to 10 wt% of a urethane oligomer and/or a reactive monomer each including a siloxane structure in its molecule; and when removing said UV-curable resin composition, the viscosity of said UV-curable resin composition is reduced. a step of applying, between said optical fibers, a liquid-form UV-curable resin composition including a siloxane structure in its molecule; and characterized by a step of removing a portion of said liquid-form UV-curable resin composition applied between said optical fibers while leaving a portion of said liquid-form UV-curable resin composition, wherein said removing is performed by rotary blades each having a recess, the rotary blades rotate in accordance with a supply speed of the optical fibers, and the rotary blades remove said liquid-form UV-curable resin composition applied between the optical fibers while leaving said liquid-form UV-curable resin composition at the recess; and a step of irradiating said liquid-form UV-curable resin composition between said optical fibers with UV rays and forming said connection parts, wherein: said including a siloxane structure in its molecule refers to a state wherein silicone is incorporated in a resin by cross-linking; said UV-curable resin composition includes, in a UV-curable resin serving as a base agent, from 0.1 wt% to 10 wt% of a urethane oligomer and/or a reactive monomer each including a siloxane structure in its molecule; and when removing said UV-curable resin composition, the viscosity of said UV-curable resin composition is reduced. said including a siloxane structure in its molecule refers to a state wherein silicone is incorporated in a resin by cross-linking; said UV-curable resin composition includes, in a UV-curable resin serving as a base agent, from 0.1 wt% to 10 wt% of a urethane oligomer and/or a reactive monomer each including a siloxane structure in its molecule; and when removing said UV-curable resin composition, the viscosity of said UV-curable resin composition is reduced.
