<P>PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition that scarcely causes the contamination and corrosion on an electronic device and in addition is served as a material for a sealing material having sufficient recyclability. Ž<P>SOLUTION: The thermoplastic elastomer composition is used in an electronic device and is produced by subjecting a raw material composition comprising (A) an ethylene-α-olefin-based copolymer rubber having a chlorine content of not more than 60 ppm as measured by X-ray fluorescence spectrometry and (B) at least one kind of thermoplastic resin selected from the group consisting of an α-olefin-based crystalline thermoplastic resin, an α-olefin-based amorphous thermoplastic resin and a cycloolefin-based thermoplastic resin, to a dynamic heat treatment, (C) in the presence of a crosslinking agent.
