Provided are a solar cell conductive paste composition capable of forming an electrode with excellent electrical characteristics and high adhesive strength and a method of manufacturing the same. A conductive paste used for forming the light-receiving surface electrode, uses various lead-free tellurium glass mixed with various lead-containing additives. Preferably, an appropriate method such as calcination or mechanochemical method is used for supporting. When forming a light-receiving surface electrode in fire-through, an erosion surface moderately having irregularities is obtained, the electrical characteristics and the adhesive strength can be satisfied.
