PROBLEM TO BE SOLVED: To provide a heat radiation member for an LED lighting apparatus made by using a thermoplastic resin composition which has a low specific gravity and exhibits superior thermal conductivity, and to provide the LED lighting apparatus which has a light weight and a long life.SOLUTION: A heat radiation member 2 which is used for an LED lighting apparatus 1 having at least either one of a single LED element and an LED package 12 made by mounting one or a plurality of LED elements as a light-emitting source, and is used for radiating heat radiated or transferred from the light-emitting source is provided with a molded body of a thermoplastic resin composition comprising 25 to 60 mol% of a unit (A) having biphenyl group, 25 to 60 mol% of a linear unit (straight chain aliphatic hydrocarbon, etc.) (B) and 0 to 25 mol% of a unit (C) having a substitute selected from a non-condensation aromatic group, a condensation aromatic group, a heterocyclic group, an alicyclic group, and alicyclic heterocyclic group which have a folding effect of a main chain. |
