ABSTRACT:
There are provided a liquid crystal polyester resin composition comprising 100 parts by weight of a liquid crystal polyester, 45 to 80 parts by weight of graphite having an average particle size of 5 .mu.m or more and 0 to 140 parts by weight of talc having an average particle size of 5 .mu.m or more, the total amount of the graphite and the talc being 55 to 185 parts by weight. There are provided a molded article such as a carrier for electronic part, a heat-resistant tray for IC, or the like, which has high heat resistance in soldering, only slight anisotropy and warpage, a surface resistivity of 1.times.10.sup.4 to 1.times.10.sup.8 .OMEGA., and an initial voltage due to electrification and a half-life (a time required for the initial voltage due to electrification to be reduced to one-half) which are controlled to be further reduced; and a liquid crystal polyester resin composition excellent in moldability which gives said molded article.
