To firmly adhere skin canvas on a belt surface conveying side by making a stage where only fluororesin is impregnated only on a roughly half part on the surface side in thickness and a remaining canvas back surface side part is completely lack of fluororesin.
A wide canvas core body 12 arranged on the back surface side of a wide conveyer belt 11 is a woven canvas low in ductility and high in strength. A skin canvas 15 having elasticity in the belt longitudinal peripheral direction is laminated and adhered on a surface of a heat resistance elastomer layer 13 with the heat resistant elastomer layer 13 as an adhesive layer. Fluororesin 17 filmed or connected and treated with a thickener as shown in a striped pattern is impregnated in a roughly half part on the surface side of canvas thickness of the skin canvas 15 woven in high density, and a canvas material extremely poor in adhesivity with other materials and restraining effusion of fluororesin remains in a state of it as it is on a roughly half part on the back surface side making contact with the elastomer layer 13 at leasy doubly used as the adhesive layer.
