<P>PROBLEM TO BE SOLVED: To provide flaky silver powder which can form a conductive film having excellent conductivity, to provide a method for producing the flaky silver powder, and to provide conductive paste. <P>SOLUTION: The flaky silver powder satisfies the following formula (1): A×A×B>50, wherein A denotes the average particle diameter (unit: μm) by a laser diffraction scattering type particle size distribution measurement method of the flaky silver powder, and B denotes the BET specific surface area (unit: m<SP POS="POST">2</SP>/g) of the flaky silver powder. In the method for producing flaky silver powder, silver powder with the average particle diameter of 1-15 μm is extended with a solvent and balls that have a diameter of 0.1-3 mm, and is subjected to flaking treatment till the average particle diameter of the silver powder reaches the maximum or passes through the maximum value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
