is made higher than the height L0 of the conical convex portion 2,
The conical protrusion is protected from external forces. (Embodiment 2) FIG. 3 is a cross-sectional view of a ferrule material for an optical connector showing another embodiment of the present invention.
In order to improve the sintering performance, when forming a ring-shaped protrusion 4 surrounding the conical protrusion 2, the outer diameter 5 of the ring-shaped protrusion is set to the outer diameter 6 of the ferrule material of the optical connector. The height L1 is the height L of the conical convex part 2.
