[PROBLEMS] To provide a method for forming a high-definition electroconductive thin line free from blurring at low cost. [MEANS FOR SOLVING PROBLEMS] A resin film having a hardness of 20 to 70, as measured by a type A measuring method specified in JIS K 6253, is formed on a surface of a resin base material. A thin line pattern is formed on the resin film using an electroconductive paste by intaglio printing or stencil printing or using an electroless plating catalyst ink by intaglio printing or stencil printing. Subsequently, a metal film is formed on the thin line pattern by plating to form an electroconductive thin line. |
