<P>PROBLEM TO BE SOLVED: To provide a molded body excellent in high thermal conductivity, electrical insulation, low density, moldability, high light stability, high whiteness and the like, and having high reflectivity. <P>SOLUTION: The high thermal conductivity resin-molded body is obtained by molding a composition which contains at least a thermoplastic polyester resin and scale-like hexagonal boron nitride powders having the number-average particle size of ≥15 μm, whiteness of ≥90 and graphitization index of ≤2.0 and has a volume ratio of the resin to the boron nitride powder of 85/15 to 25/75. The molded body has: a whiteness of ≥80 as a molding; a thermal conductivity of ≥1 W/m.K; a color difference ΔE, before and after irradiating a sample with light emitted from a 400W mercury lamp in an atmosphere at 120°C continuously for seven days from 10 cm, of ≤10; and a surface electrical resistance value of ≥1,011 Ω. <P>COPYRIGHT: (C)2012,JPO&INPIT |
