Abstract
It is an object of the present invention to suppress a coating resin from being shaved off in an event where optical fibers are sent out from a coating dice. When a Young's modulus of ultraviolet curable resinslocated on outermost layers of optical fibersis 300 MPa or more, and the Young's modulus is 300 MPa to 600 MPa, a plurality of the optical fibersin which friction force measured by the following measurement method is 0.3 N or less are arranged in parallel to one another, these respective optical fibersare fixed to one another intermittently along a longitudinal direction thereof, and adhered portionsare formed.
