A conveyor belt has a traction layer (3) in the form of a woven textile that is provided with a polymer surface coating. The surface coating is formed of a base layer (2) and a functional surface layer (1). The functional surface layer (1) has an antimicrobial additive and is substantially thinner than the base layer (2). The division of the surface coating into a base layer (2) and a functional surface layer (1) allows a effectiveness against microorganisms in the area of the conveying zone. This can be achieved by using either a lower amount of antimicrobial additive in the functional surface layer (1), being a less expensive process, and achieving just as high a concentration of antimicrobial additive. This can also be achieved by using the same amount of additive resulting in a substantially higher concentration and thus a higher effectiveness against microorganisms.
