Zusammenfassung:	A coating liquid for forming a conductive layer according to the present invention is a coating liquid for forming a conductive layer, the coating liquid containing fine metal particles, a dispersant, and a dispersion medium. In the coating liquid for forming a conductive layer, the fine metal particles contain copper or a copper alloy as a main component, the dispersant is a polyethyleneimine-polyethylene oxide graft copolymer, a polyethyleneimine moiety in the graft copolymer has a weight-average molecular weight of 300 or more and 1,000 or less, a molar ratio of polyethylene oxide chains to nitrogen atoms in the polyethyleneimine moiety is 10 or more and 50 or less, and the graft copolymer has a weight-average molecular weight of 3,000 or more and 54,000 or less.
