<p>Disclosed is a material having insulating characteristics, excellent formability and high heat conductivity. Specifically, a board-like filler (B) of 10-300 parts per weight having a heat conductivity of 3W/m·K or more and an average grain diameter of 1-300µm, and a particulate filler (C) of 10-300 parts per weight having a heat conductivity of 3W/m·K or more and an average grain diameter of 1/10-1/200 of that of the board-like filler (B) are added to a liquid crystal polymer (A) of 100 parts per weight. The total added amount of the components (B) and (C) is 20-500 parts per weight to the liquid crystal polymer (A) of 100 parts per weight, and the adding ratio of the component (B) to the component (C) is 3:1-1:3.</p>
