Abstract: A conductive paste is provided which can form electrodes in crystalline silicon solar cells at low cost while ensuring that the electrodes exhibit low contact resistance with respect to both p-type and n-type impurity diffusion layers. The conductive paste for forming a solar cell electrode includes a silver powder, a glass frit, an additive particle and an organic vehicle, the glass frit having a glass transition point of 150 to 440° C., the additive particle including an alloy material containing 20 to 98 mass % aluminum, the conductive paste including the additive particle in an amount of 2 to 30 parts by weight with respect to 100 parts by weight of the silver powder.
