摘要： 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 µm. The silver powder preferably has a tap density TD of equal to or greater than 5.0 g/cm 3 .

摘要： [Object] To provide fine particles 2 having excellent printing characteristics, thermal conductivity, and electrical conductivity.
[Solution] The fine particles 2 are flake-like. A main component of the fine particles 2 is an electrically conductive metal. A representative metal is silver. The structure of this metal is monocrystalline. An arithmetical mean roughness Ra of the surface of the fine particles 2 is not larger than 10 nm. The fine particles 2, a solvent, a binder, and a dispersant, etc., are mixed to obtain an electrically conductive paste. By using the electrically conductive paste, a pattern connecting elements is printed on a printed circuit board of an electronic device.
