Abstract

This invention offers a liquid crystal polymer which exhibits an excellent low warp and is advantageously used especially as a connector or the like. That is, a liquid crystal polymer composition in which a plate-shaped filler (B) in an amount of 5-100 parts by weight satisfying the following formulae (1) and (2) and having an average particle diameter of 0.5-100 &mgr;m is compounded with 100 parts by weight of a liquid crystal polymer (A).D/W≦5  (1)3≦W/H≦200  (2)wherein D is the maximum particle diameter of the plate-shaped filler (B), and the direction of the diameter D is defined as “x”; W is a particle's diameter which is in the direction y at the right angle to the direction x; and H is a thickness of the particle in the direction of z which is vertical to the xy-plane.
