发明名称 Liquid crystal polyester resin composition
摘要 A liquid crystal polyester resin composition for camera modules is used, the composition including, based on 100 parts by mass of the composition as a whole, (A) 49.5 to 69.5 parts by mass of a liquid crystal polyester, (B) 30.0 to 50.0 parts by mass of an irregular form or spherical powder having a Mohs hardness of 5 or higher and a primary particle diameter of 5 mum or less, and (C) 0.5 to 5.0 parts by mass of carbon black. The use of the resin composition allows a reduction in the amount of dust generated (particles falling off) during the production of the camera, the use of the camera, and the operation of the camera modules. The resin composition has high surface hardness, is excellent in balance between heat resistance, stiffness, moldability, and resistance to falling of particles off a surface, and causes no malfunction during autofocus control.
