Title:
CONDUCTIVE PASTE, ELECTRONIC COMPONENT, AND METHOD FOR PRODUCING ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/128957
Kind Code:
A1
Abstract:
This conductive paste contains a metal powder, a glass frit containing an Si component, and an organic vehicle. The metal powder has a flat shape wherein the ratio of the maximum length (a) to the maximum thickness (b), namely a/b is 2.5 or more; the molar quantity of SiO2 contained in the glass frit is 36-59% by mole; and the volumetric content of the glass frit is 6-11% by volume. External electrodes (5a, 5b) of a multilayer ceramic capacitor, said external electrodes using this conductive paste, have a molar quantity of SiO2 contained in a glass phase (10) of 38-60% by mole, an area occupancy by the glass phase (10) of 30-60%, and a maximum length (c) of the glass phase (10) of 5 μm or less. Consequently, there are provided: a conductive paste that is suitable for the formation of an external electrode; an electronic component such as a multilayer ceramic capacitor wherein moisture resistance and plating liquid resistance are able to be ensured without causing a structural defect and good plating adhesion is achieved even in cases where the external electrodes are reduced in the thickness; and a method for producing the electronic component.
