摘要： A mixed silver powder and a conductive paste comprising the powder are disclosed. The mixed silver powder is obtained by mixing two or more spherical silver powders having different properties from each other. The mixed powder may minimize the disadvantages of the respective types of the two or more powders and maximize the advantages thereof, thereby improving the characteristics of products. In addition, by comprehensively controlling the particle size distribution of surface-treated mixed silver powder and the particle diameter and specific gravity of primary particles, a high-density conductor pattern, a precise line pattern, and the suppression of aggregation over time can be simultaneously achieved.
