摘要： There are provided a spherical silver powder which has the same diameter as that of a spherical silver powder produced by a conventional wet reduction method and which can sufficiently sinter the silver particles thereof to cause the silver particles to be adhered to each other at a relatively low temperature to form a conductive film having a low volume resistivity when it is used for a baked type conductive paste, and a method for producing the same. A spherical silver powder, which contains a neutral or basic amino acid having a carbon number of not less than 5 in each of particles thereof and which has an average particle diameter D 50 of 0.2 to 5 µm based on a laser diffraction method, is produced by adding the neutral or basic amino acid having the carbon number of not less than 5 (such as proline, tyrosine, tryptophan, phenylalanine, arginine or histidine) to a water reaction system containing silver ions to mix a reducing agent therewith to deposit silver particles by reduction.

摘要： The present invention provides: a silver powder which enables the formation of a conductive film that has a lower resistance than ever before if used as a starting material for a conductive paste that is fired so as to form the conductive film; and a method for producing this silver powder. According to the present invention, a silver powder which has three or more peaks where the frequency is highest in the volume-based particle size distribution as measured by a dry method using a laser diffraction particle size distribution measuring instrument, while having one peak where the frequency is highest in the volume-based particle size distribution as measured by a wet method using a laser diffraction/scattering particle size distribution measuring instrument, is produced by mixing a first silver powder that has one or more peaks where the frequency is highest in the volume-based particle size distribution as measured by a dry method using a laser diffraction particle size distribution measuring instrument with a second silver powder that has two or more peaks where the frequency is highest in the volume-based particle size distribution as measured by a dry method using a laser diffraction particle size distribution measuring instrument.
