A rubber composition containing a plant oil satisfying the conditions (1)-(4): (1) it is liquid at 23° C.; (2) it has a GPC weight-average molecular weight of more than 800; (3) when it is 3-fold diluted with THF, it satisfies the following relationship with respect to the absorbances at 450 nm and 600 nm measured with a spectrophotometer: Absorbance at 450 nm−Absorbance at 600 nm 0.05; and (4) it satisfies the following relationship with respect to the weights before and after passing 100 g of the plant oil at 23-30° C. through 20 mesh plain weave wire cloth: (Weight after passing through plain weave wire cloth)/(Weight before passing through plain weave wire cloth)×100≥99.0.",
