Abstract
[Problem] To provide a multi-fiber optical connector ferrule that has low connection loss even when optical wiring is mounted on a substrate. [Solution] This multi-fiber optical connector ferrule: is obtained by molding a resin composition that includes polyphenylene sulfide; and has optical fiber insertion holesand a guide holefor guide pin insertion. The dimensional variation of the multi-fiber optical connector ferrule when heated at 260° C. is no more than 0.1%. The multi-fiber optical connector ferrule is a high-density optical connector having at least eight optical fiber insertion holes provided therein. The optical fiber insertion holes have an internal diameter of 127 μm and are provided at a pitch of no more than 250 μm.
