PROBLEM TO BE SOLVED: To provide an unvulcanized rubber sheet, etc. which excels in handling in the case of conveying, conserving especially in the case of feeding stably, quantitatively to a processing apparatus. SOLUTION: The unvulcanized rubber sheet is characterized by coating an unvulcanized rubber with a non-adhesiveness resin. As a kind of the unvulcanized rubber, for example, a natural rubber, a styrene-butadiene rubber, an SBS rubber, a hydrogenation SBS rubber, a styrene copolymerization rubber, such as a liquid polymerization styrene butadiene, and in addition to this, a polyisobutadiene rubber, an isobutylene isoprene rubber, a butadiene rubber, a polyisoprene rubber, an alfin rubber, a nitrile rubber, a fluororubber, a vinylpyridine rubber, a silicone rubber, a butadiene-methyl methacrylate rubber, an acrylic rubber, a polyurethane rubber, an ethylene-α-olefin copolymerization rubber, and an ethylene-α-olefin-non-conjugated diene copolymerization rubber are cited.
