Beschreibung
Zusammenfassung:	An object of the present invention is to provide a conductive paste having a low electrical resistance value and excellent conductivity when made into a sintered body, and a sintered body thereof. The conductive paste comprises a flaky silver powder having a median diameter D50 of 15 [mu]m or less, a silver powder having a median diameter D50 of 25 [mu]m or more, and a solvent, wherein the content of the flaky silver powder is 15 to 70 parts by mass, the content of the silver powder having a median diameter D50 of 25 [mu]m or more is 30 to 85 parts by mass with respect to 100 parts by mass of the total of the flaky silver powder and the silver powder having a median diameter D50 of 25 [mu]m or more.
