PROBLEM TO BE SOLVED: To provide a conveyor belt suitable for environmental sanitation, not contaminating a conveyed object by toxic substance or a toxic substance generation source, and emitting neither toxic substance nor endocrine disruptor even if disposing of the conveyor belt. SOLUTION: This conveyor belt including a laminate body 20 having resin layers 2, core layers 1 and adhesive layers 3 disposed between the resin layers 2 and the core layers 1. The resin layer 2 is made of a polyolefin not containing nitrogen, sulfur or a halogen. The core layer 1 is made of polyester fiber free from nitrogen, sulfur or a halogen. The adhesive layer 3 is formed by impregnating or applying, to the core layer 1a, liquid material wherein a resin consisting mainly of a styrene-ethylene-butylene-styrene copolymer, free from nitrogen, sulfur or a halogen is dissolved in a solvent free from nitrogen, sulfur or a halogen, then vaporizing the solvent. A string-like outline member 15 is made of a polyolefin free from nitrogen, sulfur or a halogen, similar to the resin layer 2. |
