ABSTRACT:
A conductive pattern forming ink for forming a conductive pattern on a substrate by a droplet discharge method, includes: metal particles; an aqueous dispersion medium in which the metal particles are dispersed; sugar alcohol derived from a disaccharide; and a polyglycerol compound having a polyglycerol skeleton. H shown in the following formula (I) is 0.10 to 0.80.H=OH(A)Mw(A)X(A)+OH(B)Mw(B)X(B)Formula(I)OH(A) represents an average number of hydroxyl groups in one molecule of the polyglycerol compound, Mw(A) represents a weight-average molecular weight of the polyglycerol compound, X(A) represents a content of the polyglycerol compound in the conductive pattern forming ink in weight percent; and OH(B) represents an average number of hydroxyl groups in one molecule of the sugar alcohol derived from a disaccharide, Mw(B) represents a weight-average molecular weight of the sugar alcohol derived from a disaccharide, and X(B) represents a content of the sugar alcohol derived from a disaccharide in the conductive pattern forming ink in weight percent.
