<P>PROBLEM TO BE SOLVED: To provide an ink for forming a conductor pattern that can be ejected stably from a droplet ejection head, and to provide a highly reliable conductor pattern, and a highly reliable wiring board having such a conductor pattern. <P>SOLUTION: An ink 1 for forming a conductor pattern 10 on a substrate by means of a droplet ejection head 110 contains metal particles, an aqueous dispersion medium into which the metal particles are dispersed, and a fatty acid ester of polyethylene glycol. The carbon number of a fatty acid composing the fatty acid ester of polyethylene glycol is 10-20. Content of the fatty acid ester of polyethylene glycol is preferably 0.1-5 wt%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
