The present invention provides a conductive pattern forming ink that has excellent storage stability and can prevent the occurrence of cracks in a formed conductive pattern. An ink for forming a conductor pattern according to the present invention is a conductor pattern forming ink for forming a conductor pattern on a substrate by a droplet discharge method, wherein the metal particles and an aqueous system in which the metal particles are dispersed. It contains a dispersion medium, a sugar alcohol derived from a disaccharide, and a polyglycerin compound having a polyglycerin skeleton, and H represented by the following formula (I) is 0.10 to 0.80. [Expression 1] (In the formula, OH (A) [pieces], Mw (A), and X (A) [wt%] respectively represent the average number, weight average molecular weight, and content of hydroxyl groups in one molecule of the polyglycerol compound. , OH (B) [pieces] X (B), and Mw (B) [wt%] represent the number, molecular weight, and content of hydroxyl groups in one molecule of sugar alcohol derived from disaccharide, respectively.
