Abstract

The present invention has the object to provide a liquid crystal polyester resin composition capable of obtaining a molded body which is not easily fibrillated, and a camera module component by molding the same. The liquid crystal polyester resin composition of the present invention contains 5 to 40 parts by volume of barium sulfate (B) having a particle size of 1 μm or less and 0.01 to 10.0 parts by volume of carbon black (C) with respect to 100 parts by volume of a liquid crystal polyester (A).

Claims

1. A liquid crystal polyester resin composition, comprising:

5 to 40 parts by volume of barium sulfate (B) having a particle size of 1 μ

m or less and 0.01 to 10.0 parts by volume of carbon black (C) with respect to 100 parts by volume of a liquid crystal polyester (A).

2. A camera module component prepared by injection molding the liquid crystal polyester resin composition according to claim 1.
