Document Type and Number:
WIPO Patent Application WO/2024/095583
Kind Code:
A1
Abstract:
Provided is a layered ceramic capacitor that makes it possible to improve moistureproofing reliability. In the present invention, a multi-layer ceramic capacitor 1 comprises a laminate 2 and an external electrode 3. The laminate 2 has an inner layer portion 11, a first side margin portion 20A and a second side margin portion 20B that are positioned on both sides of the inner layer portion 11 in the width direction W, and a pair of outer layer portions 12 that are positioned on both sides of the inner layer portion 11 in the lamination direction T and are positioned so as to be sandwiched between the side margin portions 20. The layered ceramic capacitor 1 comprises a first cover region 4A and a second cover region 4B that are made from an inorganic material and are positioned so as to span across the boundary between the first side margin portion 20A or the second side margin portion 20B and the outer layer portion 12 on the outer surface of the laminate 2. End surfaces C of the layered ceramic capacitor 1 each have a non-covered portion Ca that is not covered by the cover regions 4, said end surfaces C being connected to the external electrode 3 at the non-covered portions Ca.
