A conveyor belt is formed by covering a belt core body with a cover rubber. The cover rubber has a fine ridged/grooved structure formed on at least a portion of a surface thereof, and has a surface roughness of 1 μm or more and 12 μm or less, a degree of sharpness of 2 or more and 9 or less, and a specular gloss at an angle of incidence of 60° of 0.1 or more and 10 or less due to the fine ridged/grooved structure. The surface roughness is preferably 2 μm or more and 5 μm or less, and the degree of sharpness is preferably 3 or more and 5 or less, and the specular gloss at an angle of incidence of 60° is preferably 0.1 or more and 3 or less. Such conveyor belt is less likely to have a poor appearance due to bloom.

A conveyor belt 10 is formed with a belt core body 14 covered by a cover rubber 12. The cover rubber 12 is formed with a shock resistance performance evaluation index, i.e., the product of an elongation at break Eb, a tensile strength at break TSb, and a loss tangent tan of 6000 or greater. The loss tangent tan is the ratio between a storage modulus and a loss modulus calculated from a stress when vibrations of a predetermined frequency are applied to cover rubber 12. The measurement conditions of the loss tangent tan are determined on the basis of a speed of an impact applied under the use conditions of the conveyor belt 10.

The present invention allows the friction of the belt with the slide table to be abated as well as restrains dusts from occurring. The conveyor belt 10 for carrying a transported article mounted on the surface thereof comprises: a belt main body 1; and a lower surface layer 3 to cover the lower surface of the belt main body 1, in which the lower surface layer 3 is provided with a projective surface 4b in which a plurality of projections 4 whose peak portions 4a are formed into a curved surface shape.
