Abstract:
1. A highly thermally conductive resin molded article having a thermal diffusion anisotropy, the highly thermally conductive resin molded article comprising a resin composition, the resin composition containing at least resin (A) and plate-like hexagonal boron nitride powder (B) in a (A)/(B) volume ratio falling within a range of 90/10 to 30/70, wherein the resin (A) includes a thermoplastic polyester resin and/or a thermoplastic polyamide resin, and wherein the plate-like hexagonal boron nitride powder (B) includes agglomerated particles in a ratio of not more than 15%, the agglomerated particles being constituted by an agglomeration of a plurality of plate-like particles, the highly thermally conductive resin molded article having a thickness of not more than 1.3mm in a part of or all over a three-dimensional shape of the highly thermally conductive resin molded article, a thermal diffusivity measured in a plane direction of the highly thermally conductive resin molded article, being (i) two or more times higher than a thermal diffusivity measured in a thickness direction of the highly thermally conductive resin molded article and (ii) not less than 0.5mm the highly thermally conductive resin molded article having a volume resistivity of not less than 10
