A vulcanized thermoplastic olefinic rubber composition comprising at least one vulcanizable rubber (A) selected from the group consisting of ethylene-alpha-olefin copolymers, which contain an ethylene unit and a unit of an alpha-olefin having 3 to 20 carbon atoms, and which are produced with use of a metallocene catalyst, and an olefinic resin (B), wherein X and Y as defined below of said (A) are from 1 to 40% and from 0.02 to 0.5, respectively, <?in-line-formulae description="In-line Formulae" end="lead"?>X=(W2/W0)x100(%)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Y=W2/W1<?in-line-formulae description="In-line Formulae" end="tail"?> wherein W 1 is a weight of a swollen vulcanized rubber (A), which is obtained when (A) in an amount of W 0 is extracted with hot xylene, and W 2 is a weight measured after drying of the above-mentioned swollen vulcanized rubber (A).
