Abstract
According to the present invention, there is provided a release agent and a release sheet. The release sheet is composed of a base member and a release agent layer including the release agent. The release agent layer is provided on at least one surface of the base member. The release agent contains a poly(meth)acrylate that includes a mono or polyalkylene glycol (meth)acrylate unit having an alkyl or aryl end group (unit (A)), and an alkyl (meth)acrylate unit (unit (B)). The carbon number of the alkyl group in the unit (B) is from 1 to 30.
