Patent ID: 7736544

Claim:
An electrically conductive composition for filling via-holes formed in an electronic circuit substrate, comprising an electrically conductive metal and a vehicle, wherein the content of the electrically conductive metal is 63 vol % to-70 vol %, and the electrically conductive composition is a plastic fluid for which fluidity increases when external pressure is applied to the composition, further comprising glass powder at 0.2 to 5 wt % based on the total weight of the composition and an inorganic oxide that does not melt at a temperature of 900° C. or lower selected from the group consisting of Al 2 O 3 , SiO 2 , TiO 2 , MnO, MgO, ZrO 2 , CaO, BaO and Co 2 O 3 , a compound oxide thereof or a metal resinate at 0.1 to 10 wt % based on the total weight of the composition, wherein the vehicle is a binder resin selected from the group consisting of an ethyl cellulose resin and rosin-modified resin.
