The present invention relates to a polyamide-based thermoplastic elastomer composition [Y] in which a rubber composition [X] and a phenol resin-based crosslinking agent [IV] are dynamically crosslinked, the rubber composition [X] comprising a polyamide [I] including 30 to 100% by mole of a terephthalic acid structural unit and having a melting point of 220 to 290° C.; an ethylene-α-olefin-unconjugated polyene copolymer rubber [II] including structural units of ethylene, an α-olefin having 3 to 20 carbon atoms and an unconjugated polyene, respectively; and an olefin-based polymer [III] including 0.3 to 5.0% by mass of a functional group structural unit, (the total of [I] to [IV]: 100% by mass).
