Claim 8:
9. A rubber composition, comprising:
the rubber block copolymer constituting the molded bale according to claim 1, and
at least any one selected from the group consisting of the following (1) to (4):
(1) a rubber-like copolymer that has a random structure containing a vinyl a romatic monomer unit, and has an iodine value of 10 to 250, an ethylene structure content of 3% by mass or more, and a vinyl aromatic monomer block content of less than 10% by mass;
(2) a copolymer that has a random block containing a vinyl aromatic monomer unit, and a conjugated diene monomer block or an olefin block, and has an iodine value of 10 to 250, an ethylene structure content of 3% by mass or more, and a vinyl aromatic monomer block content of less than 10% by mass;
(3) a hydrogenated product of a conjugated diene homopolymer having an iodine value of 10 to 250, and an ethylene structure content of 3% by mass or more; and
(4) a copolymer of conjugated diene and olefin having an iodine value of 10 to 250, and an ethylene structure content of 3% by mass or more.
