PROBLEM TO BE SOLVED: To provide a formed polymer article having increased slipperiness, sticking resistance, etc., and fully exhibiting the functions of the formed polymer article and provide a weather strip for automobile. SOLUTION: At least the surface side of only the contact part of the formed polymer article obtained by the extrusion molding and vulcanization is made of a polymer material composition obtained by at least compounding 100 phr of an ethylene-α-olefin-nonconjugated polyene copolymer, >50 phr and≤120 phr of carbon black having an arithmetic average particle diameter of≥60 nm,≤100 phr of a softening agent and a thermally expansible microcapsule. A rough surface 10b caused by thermal expansion is formed on the surface of the contact part of the formed polymer article by the use of the polymer material composition, and a rough surface 10a derived from carbon is formed corresponding to the rough surface 10b caused by thermal expansion.
