PROBLEM TO BE SOLVED: To economically-advantageously and stably manufacture a heat-conductive film having both high insulation property and heat conductivity. SOLUTION: This heat-conductive film of a multilayer structure is manufactured by performing co-extrusion and film formation so that an insulation layer is arranged on one surface or each of both surfaces of a heat-conductive resin layer containing 10-90 vol.% of a filler having electric conductivity and heat conductivity. The resin constituting the heat-conductive resin layer is preferably a polyolefin resin, wherein the density, the DSC melting point and the bending elastic modulus of the polyolefin resin are preferably 0.85-0.90 g/cm<SP>3</SP>, 110-140°C, and 5-100 MPa, respectively.
