Abstract
There is provided a thermoplastic elastomer composition from which a molded article having an appearance suitable for non-painting use can be produced. In the thermoplastic elastomer composition containing at least two olefin polymers, a content of an insoluble component in ortho-dichlorobenzene at 140° C. is 20 wt % to 50 wt % and an isothermal crystallization time measured at 130° C. is 300 seconds or longer.
