Abstract

There is provided a spherical silver powder which has a good dispersibility and which is capable of obtaining a good degree of sintering even if it is used for forming a paste to be fired at a low temperature of 600 DEG C or less to form a conductor. An aqueous solution containing a reducing agent is added to a water reaction system containing silver ions, to deposit silver particles by reduction, to produce a spherical silver powder wherein a ratio (Dx/BET) of a crystallite diameter Dx (nm) to a BET specific surface area (m<SP>2</SP>/g) is in the range of from 5 to 200 and which has a crystallite diameter of not greater than 40 nm, a mean particle size of not greater than 5 μm, a tap density of not less than 2 g/cm<SP>3</SP>, and a BET specific surface area of not greater than 5 m<SP>2</SP>/g.
