Abstract
The present invention provides a thermoplastic elastomer composition containing: (A-1) a crosslinked ethylene copolymer containing monomer units derived from ethylene and monomer units derived from propylene and/or α-olefins having 4 to 10 carbon atoms, (B) a propylene polymer containing monomer units derived from propylene and having a content of the monomer units derived from propylene of greater than 50% by weight, and (E) an inorganic filler having an average particle diameter of less than 1.0 μm. In the thermoplastic elastomer composition, the content of the component (E) is 10% by weight to 23% by weight and the Shore A durometer hardness of the thermoplastic elastomer composition is 30 to 99. Molded articles formed of the thermoplastic elastomer composition are superior in adhesiveness to thermoplastic elastomer molded articles.
