Abstract
Provided are a fine silver particle ink composed of hexylamine, dodecylamine, oleic acid, fine silver particles and a solvent, in which the volume resistivity of a sintered body at 100° C. obtained after the ink is applied on a substrate by spin coating is 8 to 25 μΩcm, a sintered body thereof, and a method for producing a fine silver particle ink. When a fine silver particle ink containing coated fine silver particles is produced by a silver-amine complex decomposition method, production can be carried out smoothly. The fine silver particle ink can be sintered even at a low temperature, and a sintered body thereof has a mirror surface and low volume resistance.
