Abstract: Provided is a thermoplastic elastomer composition which exhibits excellent flexibility in a wide temperature range from ordinary temperature to low temperature, which has a flame retardancy of V-0 according to the UL94 vertical burning test, without including any halogen-based flame retardant, which is excellent in thermal conductivity, electrical insulation and electrolytic solution resistance, and which can be suitably used in a soft battery pack protection member. The present invention provides a thermoplastic elastomer composition for a battery pack protection member, including 100 parts by mass of a resin composition including (a) 20 to 80% by mass of a hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound, and (b) 80 to 20% by mass of a softening material for non-aromatic rubber, in which the total of the component (a) and the component (b) is 100% by mass; (c) 0.1 to 10 parts by mass of a modified resin; and (d) 250 to 400 parts by mass of magnesium hydroxide.
