Claims

[Scope of utility model registration request]

having a capillary insertion hole on the distal end surface and forming an optical fiber insertion center hole passing through the back wall and rear end surface of the insertion hole;
A metal sleeve in which the center line of the writing center hole and the center line of the insertion hole are aligned, and the metal sleeve is press-fitted into the metal sleeve so that its distal end surface is flush with the distal end surface of the metal sleeve. A ferrule for an optical fiber connector, which is formed by press-fitting an inner pipe having a through-hole with a diameter equal to the outer diameter of the optical fiber into the outer pipe.
