PROBLEM TO BE SOLVED: To provide a method for forming a copper circuit, which dispenses with an etching resist, high-precision printing equipment and the like, and which enables a wiring pattern to be simply drawn with a high degree of repetition accuracy through a small number of steps.SOLUTION: A method for forming a copper circuit includes: an application step of applying a copper film forming agent, which contains a copper complex for forming the copper film, onto a base material; a photoirradiation step of forming the copper film by irradiating a predetermined part of the applied copper film forming agent with light; and a cleaning step of cleaning and removing a part that is not irradiated with the light. |
