Abstract: A release agent for forming a release layer contacting with an adhesive layer, comprising (A) a polyolefin having a weight-average molecular weight of not less than 1×104, which may contain a functional group, and (B) a hydrocarbon having a viscosity of 1 to 1×104 cP as measured at 23° C. according to JIS K-7117, a weight ratio of the polyolefin (A) to the hydrocarbon (B) being 97:3 to 60:40. Such a release agent provides a novel release agent that is usable as an alternative material of a silicone-based and fluororesin-based release agents.
