Process for producing laminate, and laminate

The present invention provides a method for producing a laminate having a method laminate resin layer between them substrate and the supporting plate and is present in the manufacturing, the method comprising the steps of: the resin layer is formed on the support plate a step, and causing the resin layer to be peeled off in the form of close contact with the step of the substrate, wherein at least one of the substrate surface and the surface of the resin layer to be closely bonded prior to the step of close contact beforehand with a silicone oil or a silane coupling agent treatment processes, or in the step of forming the resin layer, the resin layer is formed of a resin containing a silicone oil or a silane coupling agent, and then, in the step of the close contact, the so that the substrate and the resin layer superimposed and close contact.
