1. A conductive paste composition for an external electrode of a multilayer ceramic capacitor, comprising a conductive base material, an organic solvent, a binder resin, and a dispersing agent,
wherein the conductive base material comprises a flake-shaped conductive powder, a spherical conductive powder, and first and second glass frits,
wherein the flake-shaped conductive powder has a larger size (D50) than the spherical conductive powder,
wherein the first glass frit comprises SiO2, SrCO3, BaCO3, Li2SO4, K2SO4, V2O5, ZnO, Al2O3, and Y2O3,
wherein the second glass frit comprises SiO2, SrCO3, BaCO3, CaF, ZnO, Al2O3, Y2O3, and L2O3.
