PROBLEM TO BE SOLVED: To provide a nano-size silver fine particle ink which consists of coated silver fine particles dispersed in a solvent, is sinterable at low temperatures and gives a sintered body having a mirror surface and a small volume resistivity and its sintered body.SOLUTION: A nano-size silver fine particle ink consists of silver fine particles dispersed in a solvent, and silver fine particles are dissolved in the solvent to a concentration of 1-50 wt.%. When the nano-size silver fine particle ink is analyzed by gas chromatography with an FID capillary, the ink contains at least hexylamine, dodecylamine and oleic acid. The mol ratio of hexylamine to dodecylamine is 3:1 to 60:1, and the amount of oleic acid is 0.02-0.30 mmol/g to the mass of silver. |
