Title:
CONDUCTIVE PASTE
Document Type and Number:
WIPO Patent Application WO/2024/004391
Kind Code:
A1
Abstract:
Provided is a conductive paste for an internal electrode of a layered ceramic capacitor, said conductive paste being capable of maintaining relatively high coverage even if the internal electrode constitutes a thin layer. The conductive paste is for forming an internal electrode (4, 5) of a layered ceramic capacitor (1) fabricated through a firing step and comprises a conductive metal powder, a ceramic powder, an organic solvent, and an organic binder. The conductive metal powder contains copper. At least a portion of the ceramic powder consists of an ABO3 type oxide having a specific ion radius in which the ratio of the ion radius in the 6-coordination of the element at the A site in ABO3 with respect to the ion radius in the 6-coordination of copper is 0.96-1.04.
