Abstract: A thermoplastic elastomer composition which comprises 100 parts by weight of an ethylene/propylene/unconjugated diene terpolymer or ethylene/propylene bipolymer, 10 to 150 parts by weight of a crystalline polyolefin resin having a melt flow rate (in accordance with JIS K7210, 230°C, 21.18 N) of 0.1 to 100 g/10 min, 20 to 150 parts by weight of a nonaromatic softener having a dynamic viscosity at 40°C of 300 mm /s or higher, and 0.1 to 10 parts by weight of an organic peroxide, and has a hardness as measured with a JIS type-A durometer of 30 to 70 degrees. This thermoplastic elastomer composition has excellent sealing properties. Also provided are a molded gasket obtained through a simplified production step and a sealing structure comprising the gasket.
