The purpose of the present invention is to provide: a rubber composition having excellent adhesion to a metal surface not only when vulcanized using steam vulcanization, but also when vulcanized using oven vulcanization, and also exhibiting excellent adhesion when left in a hot and humid environment after vulcanization; and a layered body provided with a reinforcing layer having a metal surface and a rubber layer formed using the rubber composition. This rubber composition contains a diene-based polymer including butadiene rubber, and a polyhydric alcohol, the content of the polyhydric alcohol being 0.5 parts by mass to 14 parts by mass with respect to 100 parts by mass of the diene-based polymer. |
