。(Effects of the Invention) As explained above, in the present invention, when molding the optical multi-core plastic connector body, a master bin is used to position the mating sleeve in the mold hole of the mold, and the fitting sleeve is positioned inside the optical multi-core plastic connector body. Since the pin fitting hole of the fitting sleeve can be accurately positioned, the axis of the optical fiber when connecting the connector can be precisely aligned. Furthermore, since the present invention uses a mating sleeve made of metal or ceramics, the optical multi-core plastic connector always has a pin-fitting hole with a constant inner diameter regardless of the type of plastic material of the optical multi-core plastic connector body. It can be manufactured extremely easily. Furthermore, using such a fitting sleeve improves the alignment accuracy of the optical fiber and prevents an increase in coupling loss, and also prevents wear of the bottle fitting hole, damage to its entrance, or moisture absorption in the bottle fitting hole. It is also possible to prevent changes in pore diameter due to
