It is an object of the present invention to provide an olefin thermoplastic elastomer composition which, through dynamic crosslinking of an olefin resin and an ethylene-alpha-olefin copolymer rubber as polymer components, has excellent appearance of the extrusion molding while also having excellent physical properties such as compression set and tensile strength. The present invention is directed to a method for producing a thermoplastic elastomer composition having the steps of: dynamically heat treating the following components (A) to (D); adding a component (E) to a resulting composition; and kneading the resulting mixture, and a thermoplastic elastomer composition obtained by the production method, (A): 40 to 95 parts by weight of an ethylene-alpha-olefin-based copolymer rubber; (B): 5 to 60 parts by weight of a polyolefin-based resin; (C): 0.1 to 20 parts by weight of a halogenated alkylphenolic resin-based crosslinking agent; (D): 0.001 to 0.7 part by weight of iron oxide; and (E): 0.1 to 20 parts by weight of a halogen capturing agent.
