Abstract
A conductor paste for plugging a through-hole in a ceramic substrate which includes an electrically conductive powder having a metal powder as its main component, a swelling agent and a vehicle, and may also include adhesion improvers. After sintering the conductor paste, a conductor plug is created which will not fall out of the through-hole, is resistant to chipping during the leveling process and may be gas impermeable.
