Abstract
There are provided an inorganic compound-containing thermoplastic resin composition that practically retains various properties of a general-purpose resin such as mechanical properties and moldability and has excellent thermal conductivity, and a highly thermally conductive molded article molded using the resin composition.
In a polymer alloy comprising a thermoplastic resin excluding a thermoplastic polyester resin, a thermoplastic polyester resin and a highly thermally conductive inorganic compound, the thermoplastic polyester resin forms a continuous phase and the highly thermally conductive inorganic compound is preferentially present in a phase other than the thermoplastic resin excluding a thermoplastic polyester resin. Therefore, the composition and the highly thermally conductive molded article molded using the resin composition can have a thermal conductivity improved only by adding a relatively small amount of the highly thermally conductive inorganic compound.
