Rubber composition, laminated body, and conveyor belt

Abstract

Provided is a rubber composition capable of suppressing deterioration of adhesiveness to a reinforcing member even in the case of having been subjected to repeated flex fatigue. The rubber composition is obtainable by compounding a rubber component containing a diene based rubber, a wet silica, a carbon black, and a calcium carbonate, wherein: a compounding amount of the wet silica is 3 parts by mass or more per 100 parts by mass of the diene based rubber; a nitrogen adsorption BET specific surface area of the carbon black is 8 m2/g or more and 100 m2/g or less; and the following formula 0.5X+28≤Y≤X+88 is satisfied, where X represents the nitrogen adsorption BET specific surface area of the carbon black in terms of m2/g, and Y represents a compounding amount of the calcium carbonate in terms of parts by mass per 100 parts by mass of the diene based rubber.
