The present invention provides a molded bale of a rubber composition that is difficult to cold flow, and is difficult to be thermally deteriorated during production, and in which rigidity at 50° C. of a rubber composition for crosslinking obtained therefrom is difficult to be low, and change of tensile strength of the rubber composition for crosslinking after thermal history is small. The rubber composition contains: a rubber-like polymer (A) having an iodine value of 10 to 250, 3% by mass or more of an ethylene structure, and less than 10% by mass of a vinyl aromatic monomer block; aluminum (B); and nickel and/or cobalt (C), in which a content of the aluminum (B) is 2 ppm or more and 200 ppm or less, and a content of the nickel and/or cobalt (C) is 3 ppm or more and 100 ppm or less.
