Claim 3:
4. The ethylene/α-olefin/non-conjugated polyene copolymer (S) according to claim 1, further comprising a constitutional unit derived from a non-conjugated polyene (D) having only one partial structure selected from the group consisting of the general formulas (I) and (II) in a molecule in a weight fraction of 0 to 20 wt % (provided that the sum of the weight fractions of (A), (B), (C), and (D) is 100 wt %, and satisfying the following requirement (viii):
(viii) the weight average molecular weight (Mw), the weight fraction of the constitutional unit derived from the non-conjugated polyene (C) (weight fraction of (C) (wt %)), the weight fraction of the constitutional unit derived from the non-conjugated polyene (D) (weight fraction of (D) (wt %)), the molecular weight of the non-conjugated polyene (C) (molecular weight of (C)), and a molecular weight of the non-conjugated polyene (D) (molecular weight of (D)) satisfy the following expression (4):

4.5≤Mw×{(Weight fraction of(C)/100/Molecular weight of(C))+(Weight fraction of(D)/100/Molecular weight of(D))}≤45  Expression (4),
