The present invention relates to a thermoplastic elastomer composition, its foaming material, and its production method. The thermoplastic elastomer composition comprises an ethylene-based copolymer (A); an olefin block copolymer (B), the olefin block copolymer being different from the ethylene-based copolymer; an unsaturated aliphatic rubber (C); and a bridge Agent (D), wherein the weight ratio of the unsaturated aliphatic rubber (C) to the olefin block copolymer (B) is 1:1.5 to 1:5. |
