Provided is a silver powder which has an appropriate viscosity range at the time of paste production, can be easily kneaded, and prevents the occurrence of flakes. The silver powder to be used has a specific surface area ratio SAB/SAS of 0.5 to 0.9, wherein SAB is a specific surface area measured by the BET method, and SAS is a specific surface area calculated from a mean primary-particle diameter DS measured with a scanning electron microscope. Furthermore, the silver powder preferably has a degree of aggregation of 1.5 to 5.0, the degree being obtained in such a manner that a volume median diameter D50 measured by laser diffraction scattering is divided by the foregoing Ds.
