An electrically conductive paste composition comprises: (a) silver powders comprising spherical silver powders having a mean particle size (D50) of over 0.1 μm and no more than 5 μm and flake-shaped silver powders having a mean particle size of no more than 10 μm; and (b) binder resins comprise (b-1) aliphatic thermoplastic resin and (b-2) self-polymerizing thermosetting resin; wherein the content of the silver powders is no more than 60 wt % based on the total weight of the paste composition, wherein the weight ratio of the aliphatic thermoplastic resin for the self-polymerizing thermosetting resin ((b-1)/(b-2)) is 99/1-67/33 and wherein the weight ratio of the silver powders for the binder resins ((a)/(b)) is 94/6-85/15.
