PROBLEM TO BE SOLVED: To provide a conductive paste exhibiting high conductivity even when the content of silver powder is low. SOLUTION: The conductive paste composition comprises a flaky silver powder A having an average particle size of 3 to 8μm, a specific surface area of 1.5 to 4.0 m<SP>2</SP>/g, and an apparent density of 0.4 to 1.1 g/cm<SP>3</SP>, a flaky silver powder B having an average particle size of 3 to 10μm, an specific surface area of 0.6 to 1.2 m<SP>2</SP>/g, and an apparent density of 1.5 to 2.1 g/cm<SP>3</SP>, and a resin. The conductive paste composition contains the flaky silver powder A of 30 to 95 pts. wt., taking the total weight of the flaky silver powders A and B as 100 parts. The composition contains the flaky silver powders A and B in total at 35 to 85 wt% based on a solid component of the conductive paste. COPYRIGHT: (C)2004,JPO
