PROBLEM TO BE SOLVED: To provide conductive inks including silver nanoparticles and a gelling agent for gravure printing and flexographic printing.SOLUTION: A silver nanoparticle conductive ink includes silver nanoparticles, a gelling agent and a solvent. The conductivity is about 1.0×104 to about 4.0×105 (S/cm). The silver nanoparticles have an average size of 0.5 to 100.0 nm, and account for 50.0 to 95.0 wt.% of the conductive ink. 【課題】グラビア印刷およびフレキソ印刷のための銀ナノ粒子とゲル化剤とを含む導電性インクの提供。【解決手段】銀ナノ粒子と、ゲル化剤と、溶媒とを含み、導電性が約１．０?１０４〜約４．０?１０５（Ｓ／ｃｍ）であり、平均粒径が０．５〜１００．０ｎｍであり導電性インクの５０．０〜９５．０重量％含まれる、銀ナノ粒子導電性インク。【選択図】なし
