Disclosed is a thermoplastic elastomer composition which has a mechanical strength equivalent to or higher than those of conventional thermoplastic elastomer compositions, while further having excellent heat resistance and oil resistance. Also disclosed are a method for producing such a thermoplastic elastomer composition and a formed article obtained by using such a thermoplastic elastomer composition. The thermoplastic elastomer composition is characterized by containing a thermoplastic resin having a polar group and an ethylene/alpha-olefin elastomer having a functional group. The ethylene/alpha-olefin elastomer having a functional group is preferably a random copolymer obtained by copolymerizing an ethylene, an alpha-olefin having 3-10 carbon atoms, an unsaturated monomer having a functional group, and if necessary an unconjugated diene.
