Patent ID: 7285232

Claim:
A conductive paste comprising: conductive powder; glass powder; and an organic vehicle, wherein the glass powder comprises about 10% to 31% of B 2 O 3 , about 65% to 86% of SiO 2 , and more than about 0.5% to less than about 5% of M 2 O on a weight basis, where M represents an alkali metal element and wherein the conductive powder contains spherical particles with an average particle size of about 0.5 to 1.0 μm and flat particles having an average particle size of about 1.5 to 5.0 μm and an aspect ratio of about 5:1 to 70:1, the aspect ratio being the ratio of the maximum diameter to the average thickness, and wherein the ratio of the amount of the spherical particles to that of the flat particles ranges from about 1:4 to 4:1 on a weight basis.
