PROBLEM TO BE SOLVED: To provide silver fine particles which have a small particle diameter and a shape of a high aspect ratio, can be fused and sintered at low temperatures and can form an electrically conductive thin film having excellent optical transparency and electrical conductivity, and to provide a method of relatively easily producing the silver fine particles. SOLUTION: Each of the silver fine particles is almost a planar particle having two principal planes, and has a thickness of≤50 nm and a major axis of≤5,000 nm. In the method of producing the silver fine particles, a solution obtained by dissolving at least a polymer compound, a reducing agent and a silver salt is stirred at 25 to 60°C.
