The problem addressed by the present invention is to provide a rubber composition having excellent adhesion to a metal member. The rubber composition (a rubber composition not containing a thiuram-based compound vulcanization accelerator) includes a rubber component, a rubber-metal adhesion accelerator, and a vulcanization accelerator other than a thiuram-based compound, in which the rubber component includes EPDM in an amount of 20 parts by mass or more with respect to 100 parts by mass of the rubber component. And the rubber-metal adhesion promoter includes one or more compounds selected from the group consisting of aliphatic carboxylic acids/metal salts (1) and compounds (2) represented by formula A: [(RCOO) xMO] 3Z, the aliphatic carboxylic acids of the metal salts (1) each having 2-25 carbon atoms, and the metals of the metal salts (1) each being Bi, Zn, Cu, Sb, Ag, Nb, or Zr. In formula (A), (RCOO) is a residue of an aliphatic carboxylic acid having 2 to 25 carbon atoms, M is Bi, Zn, Cu, Sb, Ag, Nb, or Zr, x is an integer from 1 to (valence of M)-1, and Z is a structure selected from formulae (z-1) to (z-4),

    本发明解决的问题为提供一种具有优异的对金属构件的粘接性的橡胶组合物。该橡胶组合物(是不包含秋兰姆系化合物硫化促进剂的橡胶组合物)包括橡胶组分、橡胶‑金属间粘接促进剂、和秋兰姆系化合物以外的硫化促进剂,其中橡胶组分以相对于100质量份的橡胶组分为20质量份以上的量包括EPDM,并且橡胶‑金属间粘接促进剂包括选自脂肪族羧酸/金属盐(1)和由式A:[(RCOO)xMO]3Z表示的化合物(2)中的一种以上的化合物,金属盐(1)的脂肪族羧酸各自具有2‑25个碳原子,金属盐(1)的金属各自为Bi、Zn、Cu、Sb、Ag、Nb、或Zr。式(A)中,(RCOO)为具有2‑25个碳原子的脂肪族羧酸的残基,M为Bi、Zn、Cu、Sb、Ag、Nb、或Zr,x为1至(M的化合价)‑1的整数,并且Z为选自式(z‑1)至式(z‑4)中的结构,
