<p>PROBLEM TO BE SOLVED: To provide a silver ink composition capable of forming, without performing a high-temperature heat treatment, metallic silver having a sufficient electroconductivity; and a conductor and communication equipment each obtained by using the silver ink composition.SOLUTION: A silver ink composition is obtained by mixing: a silver carboxylate including a group expressed by the formula -COOAg; at least one type of nitrogen-containing compound selected from the group consisting of amine compounds and quaternary ammonium salts each having 25 or fewer carbon atoms, ammonia, and ammonium salts obtained as a result of reactions of the amine compounds or ammonia with acids; and at least one type of reducible compound selected from the group consisting of oxalic acid, hydrazine, and compounds expressed by the following general formula (5) (in the formula, Rexpresses an alkyl group having 20 or fewer carbon atoms, alkoxy group, N,N-dialkylamino group, hydroxyl group, or amino group). A conductor obtained by using the silver ink composition so as to form metallic silver is also provided: H-C(=O)-R(5).</p> |
