The present invention relates to a thermoplastic elastomer composition, a method for producing the same, and a molded article, the composition including: a crystalline olefin resin (A) having a melting point of 100°C or more; an olefin resin (B) satisfying requirements (B-1) to (B-3); and an ethylene/±-olefin copolymer (C), wherein the weight ratio of (A)/((B) + (C)) is from 70/30 to 30/70, and the weight ratio of (B) / (C) is from 100/0 to 1/99: (B-1) the resin (B) has a main chain composed of an ethylene copolymer and a side chain composed of an ethylene polymer or a propylene polymer, the ethylene copolymer includes repeating units derived from ethylene and repeating units derived from at least one ±-olefin selected from ±-olefins having from 3 to 20 carbon atoms, and the repeating units derived from the ±-olefin are contained within the range of from 10 to 50 mol% with respect to the total repeating units contained in the main chain; (B-2) the melting point as measured by DSC is from 60°C to 170°C; and (B-3) Tg as measured by DSC is from -80°C to -30°C.
