PROBLEM TO BE SOLVED: To provide an insulating and thermally-conductive resin composition that is suitable for extrusion molding by adding an acrylic molding modifier to a thermally-conductive resin for injection molding, and also to provide an extrusion molded product having good surface appearance, insulation properties, and thermal conductivity. SOLUTION: The thermal conductivity is at least 1 W/m.K when a thermally-conductive inorganic filler and at least two acrylic molding modifying aids that improve extrusion moldability are blended into a polymer matrix, and at least 25 vol% relative to the total is filled with the inorganic filler. The acrylic molding modifying aids include at least one acrylic polymer external lubricant and at least one acrylic polymer processing aid. At least one of the acrylic polymer processing aids includes an epoxy group and has an epoxy value in the range of 1.0 meq/g or less relative to the total acrylic molding modifying aids.
