Summary: | [Object] The invention provides a thermal storage medium composition capable of forming a thermal storage medium which is free from phase separation or liquid phase bleeding and is excellent in shape retention properties even at or above the maximum crystal transition temperature of a paraffin compound and further exhibits excellent fluidity when being shaped. [Solution] A thermal storage medium composition includes 100 parts by mass of a hydrogenated diene copolymer and 50 to 4000 parts by mass of a paraffin compound, the hydrogenated diene copolymer being a conjugated diene copolymer that is obtained by hydrogenating a block copolymer which includes a block (A) that contains structural units (a-1) derived from a conjugated diene compound and has a vinyl bond content of not more than 20 mol%, and a block (B) that contains structural units (b-1) derived from a conjugated diene compound and has a vinyl bond content of 30 to 95 mol%, the hydrogenation ratio with respect to the double bonds derived from the conjugated diene compounds being not less than 90%. |
