Abstract: Silver powder includes multiple particles 2 containing silver as a main component. A ratio of the number of particles 2 which are flake-like and each of which has a monocrystalline structure and has a largest plane that is a lattice plane (111), to the total number of particles, is not less than 95%. The silver powder is water-dispersible. In the silver powder, a median size D50 is not less than 0.1 ?m and not greater than 10 ?m, a standard deviation of particle sizes is not greater than 5 ?m, an average thickness Tave is not greater than 300 nm, and an aspect ratio (D50/Tave) is not less than 4.

Abstract: A silver powder includes a large number of particles. The particles include polyhedral particles 2. The ratio P1 of the number of the polyhedral particles 2 to the total number of the particles is equal to or greater than 80%. Each polyhedral particle 2 has a body containing silver as a main component, and a coating layer covering a surface of the body and containing organic matter as a main component. Each polyhedral particle 2 has an aspect ratio of equal to or less than 3.0. The content P2 of the organic matter in the silver powder is preferably equal to or less than 0.5% by weight. The silver powder preferably has a median diameter D50 of equal to or less than 0.5 ?m. The silver powder preferably has a tap density TD of equal to or greater than 5.0 g/cm3.
