Title:
ELECTRONIC COMPONENT AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3458701
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain an electronic component, capable of suppressing the ion migration of metal which constitutes the surface of an electrode and has high reliability.
SOLUTION: First and second external electrodes 4 and 5 are formed not only on end surfaces 2a and 2b of a ceramic sintered body 2, but also on an upper surface 2c, a lower surface 2d and both side surfaces. The external electrodes 4 and 5 have the structure so that first metal layers 4a and 5a, second metal layers 4b and 5b and third metal layers 4c and 5c are laminated sequentially. The second metal layers 4b and 5b are constituted of the metal, wherein migration is hard to occur. Then, at least one of the external electrodes 4 and 5, the second metal layers 4b and 5b are exposed, so that the third metal layers 4c and 5c do not reach the end edges 4d and 5d of the external electrodes 4 and 5, thus forming a laminated capacitor 1.
