  • Patent number: 7423220
    Abstract: A conductive paste for multilayer electronic components which is to be directly printed on a ceramic green sheet, the conductive paste contains a conductive powder, a resin and an organic solvent, wherein the organic solvent contains at least one solvent selected from an alkylene glycol diacetate and an alkylene glycol dipropionate. A multilayer electronic component is obtained by firing at high temperature an unfired laminate prepared by alternately stacking ceramic green sheets and internal electrode paste layers in which each of the internal electrode paste layers is formed by the above conductive paste. The conductive paste has appropriate viscosity characteristics and long-term stability, which allows manufacturing highly reliable multilayer electronic components having excellent electrical characteristics, without causing sheet attack.
