Abstract

A method for manufacturing a resin thin film of the present invention includes supplying a liquid resin material and a gas to a two-fluid nozzle by pressure; ejecting the resin material in the form of atomized particles toward a heating member by the two-fluid nozzle, thereby adhering the resin material to the heating member; or mixing a liquid resin material with a gas; ejecting the resin material in form of atomized particles toward a heating member that is provided under reduced pressure, thereby adhering the resin material to the heating member; and evaporating the resin material on the heating member to obtain the evaporated resin material. Thus, the present invention can provide a resin thin film having a uniform thickness stably with simple means at a low cost. The resin thin film obtained by the present invention can be used in a wide range, for example a magnetic recording medium such as a magnetic tape, a wrapping material, and an electronic component.
