PROBLEM TO BE SOLVED: To provide an ethylene-α-olefin nonconjugated polyene copolymer rubber pellet which hardly causes blocking, and to provide a method for manufacturing thermoplastic elastomer using the same.SOLUTION: A rubber pellet includes an ethylene-α-olefin nonconjugated polyene copolymer including ethylene [A], α-olefin [B] of the number of carbon atoms 3 to 20, and nonconjugated polyene copolymer including one structural unit that originates in nonconjugated polyene [C-1] that contains only one partial structure shown by a formula (I) or (CH=CH-)- in a molecule. A molar ratio ([A]/[B]) of the structural unit that originates in the ethylene [A] included in the ethylene-α-olefin nonconjugated polyene copolymer, to the structural unit that originates in the α-olefin [B], is 75/25 to 90/10 in the rubber pellet. |
