Abstract
A new dendritic silver powder can be mixed with a synthetic resin to give electroconductive films having sufficient electroconductivity. Even when the films vary in thickness, the electroconductivity of the films can be maintained. The volume-cumulative particle diameter D50 (referred to as 'D50D') determined by adding the silver powder to water containing a dispersant, applying 300-watt ultrasonic waves to the resultant mixture for 3 minutes, and examining the dispersion with a laser diffraction/scattering type particle size analyzer is 1.0-15.0 μm and that the ratio of the volume-cumulative particle diameter D50 (referred to as 'D50N') determined by adding the silver powder to the water containing a dispersant and examining the mixture under the same conditions as for the D50D except that no ultrasonic waves are applied, to the D50D, D50N/D50D, is 1.0-10.0.
