PROBLEM TO BE SOLVED: To obtain a heat-conductive molding that has excellent thermal conductivity performance and readily increases handleability. SOLUTION: The heat-conductive molding comprises a heat-conductive composition composed of (a) a thermoplastic silicone resin that is constituted of a copolymer consisting of an RSiO<SB>3/2</SB>unit and an R<SB>3</SB>SiO<SB>1/2</SB>unit and has 50-70°C heat softening temperature, (b) a branched polyorganosiloxane resin that is constituted of a copolymer consisting of an RSiO<SB>3/2</SB>unit, an R<SB>3</SB>SiO<SB>1/2</SB>unit and an R<SB>2</SB>SiO<SB>2/2</SB>unit and has 25-45°C heat softening temperature, (c) silicone crude rubber constituted of a copolymer consisting of an R<SB>3</SB>SiO<SB>1/2</SB>unit and R<SB>2</SB>SiO<SB>2/2</SB>unit and (d) a heat-conductive filler.
