  In a method of manufacturing a thin-film polymer multi-layer capacitor, in a vacuum chamber, a resin thin film layer forming step of forming a resin thin film layer by forming a monomer layer by vapor-depositing a monomer and thereafter by curing the monomer layer by irradiating an electron beam onto the monomer layer, and a metal thin film layer forming step of forming a metal thin film layer by vapor-depositing a metal material are alternately performed on a rotary drum thus forming a multi-layer body in which the resin thin film layer and the metal thin film layer are alternately laminated on the rotary drum. In the resin thin film layer forming step, the monomer layer is formed using a dimethacrylate compound having an alicyclic hydrocarbon skeleton expressed by a following chemical formula (1) as the monomer. wherein, symbol A indicates an organic group containing alicyclic hydrocarbon.
