A conveyor belt obtained by bonding together conveyor belts to be adhered using an adhesive rubber is provided. The conveyor belts to be adhered include a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X1), and carbon black (Y1), the organic peroxide (X1) being contained in an amount of from 0.011 to 0.020 molar equivalents relative to the ethylene-α-olefin copolymer in the conveyor belts to be adhered. The adhesive rubber includes a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X2), and carbon black (Y2), the organic peroxide (X2) being contained in an amount of from 0.017 to 0.022 molar equivalents relative to the ethylene-α-olefin copolymer in the adhesive rubber. A content ratio (X2/X1) of the organic peroxide (X2) to the organic peroxide (X1) is from 1.20 to 2.00.
