<p>Provided are: a resin composition with which a heat dissipation component having good thermal conductivity can be manufactured; and a heat dissipation component comprising the resin composition. Specifically provided is a resin composition containing 20 mass% to 59 mass% of a thermoplastic resin (A), 1 mass% to 10 mass% of carbon fibers (B), which have a thermal conductivity of at least 150 W/m∙K, and 40 mass% to 70 mass% of graphite particles (C). (However, the total weight of (A), (B) and (C) is set at 100 mass%.) The thermoplastic resin (A) contains: a propylene resin (A1) having a melt float rate of 1.0 g/10 minutes to 200 g/10 minutes, as measured at 230°C with a 21.18 N load; and an ethylene resin (A2) with a melt flow rate of 5.0 g/10 minutes to 300 g/10 minutes, as measured at 190°C with a 21.18 N load, and having a density of 930 kg/m3 to 990 kg/3. Further provided is a heat dissipation component comprising the resin composition.</p> |
