Abstract

A thermally conductive polymer molded article formed by molding a thermally conductive composition which comprises a liquid crystalline polymer and thermally conductive filler having magnetic anisotropy, wherein the liquid crystalline polymer and the thermally conductive filler are oriented in a predetermined direction by a magnetic field. The thermally conductive composition contains 100 parts by weight of the liquid crystalline polymer and 5 to 800 parts by weight of the thermally conductive filler having magnetic anisotropy. The thermally conductive filler has a thermal conductivity in at least one direction higher than the thermal conductivity of the liquid crystalline polymer.
