Resin composition for optical communication component and optical communication component using the resin composition

A resin composition for an optical communication component comprising:

• a base resin containing a polyether ether ketone resin as a main component;
• and
• amorphous silica, wherein
• a content of the amorphous silica in the resin composition is 55 to 75 mass %,
• a circularity of the amorphous silica is 0.80 or more,
• the base resin contains a polyphenylene sulfide resin of 2 mass % or more and 20 mass % or less,
• a content of the base resin in the resin composition for the optical communication component is 25 to 45 mass %,
• the polyphenylene sulfide resin contains a repeating unit of phenylene sulfide in an amount of 80 mol % or more, and
• the base resin further contains at least one type of resin selected from a group consisting of a liquid crystalline resin having a melting point of 300° C. or higher, a polyarylene sulfide resin, a polyethersulfone resin, and a polyetherimide resin.
