Abstract:
An electroconductive paste useful for forming a via hole conductor in a method for manufacturing a multilayer ceramic electronic part comprising manufacturing a raw laminate comprising laminated ceramic green sheets including a ceramic green sheet with said via hole conductor therein, and cutting said raw laminate at an area where said via hole conductor is located and exposing part of said via hole conductor on the cut surface, so that said via hole conductor is converted to an external electrode terminal,the paste comprising: from about 5% to 18% by weight of an organic vehicle comprising a solvent and a binder; from about 80% to 93% by weight of an electroconductive metal powder in a spherical or granular shape and with a particle diameter in the range of about 0.1 to 50 &mgr;m; and from about 2% to 10% by weight of a polypropylene resin powder that is insoluble in said solvent and has a low level of water absorption and which has a particle diameter in the range of about 0.1 to 50 &mgr;m.
