摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of short-circuiting failure by preventing a sheet attack phenomenon from occurring when manufacturing a laminated electronic component and the transfer of a solvent between green sheets. SOLUTION: A first paste film containing first resin is formed on a support (step S2). A second paste film containing a second resin that is polymerizable to the first one is formed on the first paste film in a non-dried state (step S3). The green sheet is formed by polymerizing the first and second resins (step S4). Then, an electrode pattern layer is formed on the surface of the green sheet (step S5). In this case, although the step for forming the electrode pattern layer becomes a so-called Wet-on-Dry system, the green sheet has already been cured by two-pack polymerization when the electrode pattern layer is formed, thus preventing the sheet attack phenomenon from occurring.
