摘要： Provided is a conveyor belt that has sufficient stretchability and elasticity, and sufficient strength, and is capable of reliably conveying an object to be conveyed even in inclined conveyance. The conveyor belt includes: a stretchable knitted fabric 15; an elastic layer 14 that is provided on an upper surface of the knitted fabric 15 and is made of a first thermoplastic material; and a surface resin layer 20 that is provided on an upper surface of the elastic layer 14, is made of a second thermoplastic material having hardness lower than hardness of the first thermoplastic material, and the surface resin layer 20 includes a conveying surface 21 having unevenness. Tensile strength of the conveyor belt is 3.5 to 35 MPa, and a coefficient of static friction of the conveying surface 21 is 0.5 to 1.0.

摘要： A conveyor belt makes contamination of the conveyor belt and conveyance objects less noticeable. A conveyor belt has a structure in which a colorless transparent belt body and a black resin layer that exhibits black color are overlaid on each other and is observed as a black belt. The black resin layer is provided on a surface opposite to a carrying surface of the belt body. The black resin layer is formed in black by blending a conductive filler in the resin and is added with conductivity.
