Patent ID: 8469602

Claim:
An optical fiber connecting part for a tape-like optical fiber, the optical fiber connecting part comprising: a ferrule; and a guide bore, which is formed to penetrate through the ferrule from an end face on a side of one end to another end face on a side of another end of the ferrule, and configured to guide the tape-like optical fiber to be inserted from the side of the one end of the ferrule toward the end face on the side of the another end of the ferrule, the guide bore comprising: an optical fiber insertion hole provided on the side of the one end, through which the tape-like optical fiber is inserted into the ferrule; a light input/output bore provided on the side of the another end of the ferrule and having an inner diameter smaller than an inner diameter of the optical fiber insertion hole, through which a light is input and output at the end face on the side of the another end of the ferrule; and a shape-changing bore provided between the optical fiber insertion hole and the light input/output bore to communicate therebetween, a shape of which is changed such that an inner diameter of the shape-changing bore is slowly reduced from the optical fiber insertion hole toward the light input/output bore, wherein the shape of the shape-changing bore is changed such that a center position of the light input/output bore is shifted from a center position of the optical fiber insertion hole along a thickness direction and a width direction of the tape-like optical fiber.
