More Information
Summary:The present invention provides a silver powder that has an appropriate viscosity range at the time of paste production, can be easily kneaded, and prevents flake occurrence. The silver powder has a dibutyl phthalate absorption amount, measured by a method of JIS-K6217-4, of 7.0 to 9.5 ml/100 g, and has an oil absorption profile at the time of measurement of the absorption amount, having two peaks, or one peak having a half width of not more than 1.5 ml/100 g.
