Provided are: a liquid-crystal polymer composition capable of suppressing the production of particles when used as a member for a camera module and capable of reducing the kinetic coefficient of friction and the static coefficient of friction of the member; a molded liquid-crystal polymer body using the liquid-crystal polymer composition; and an electrical/electronic appliance with the molded liquid-crystal polymer body. The liquid-crystal polymer composition contains a liquid-crystal polymer (A), a fluorine-contained resin (B), and a reinforcing material (C), wherein a surface of the reinforcing material (C) is at least partly covered with a treated layer made of a hydrophobic surface treatment agent.

Liquid-crystal polymer composition, molded liquid-crystal polymer, and electrical/electronic appliance

The present invention provides a polyarylene sulfide resin composition which shows high dielectric constant and low dielectric dissipation factor, has excellent moldability, and has improved corrosive property to metal parts. More specifically, to 100 parts by weight of (A) polyarylene sulfide resin, compounded are 10 to 400 parts by weight of (B) an alkaline earth metal titanate showing 50 or higher relative dielectric constant and 0.05 or lower dielectric dissipation factor at 1 MHz, and containing less than 500 ppm of metal ion which is extracted by hot water; and 0.01 to 15 parts by weight of (C) one or more compound selected from hydroxides and oxides of alkaline earth metals.
