Title:
CERAMIC ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2007/072617
Kind Code:
A1
Abstract:
A ceramic electronic component in which the part wetted with a conductive paste
by immersion method can be stopped at a predetermined position and an external
electrode can be formed with high dimensional precision. A ceramic electronic
component wherein external electrodes (31) formed of a conductive paste are
provided at the opposite ends of a ceramic laminate (10) incorporating a coil
(L). The ceramic laminate (10) consists of a main portion (11) and end portions
(12, 12). The end portion (12) has a porosity of 10 vol% or less whereas the main
portion (11) has a porosity of 30-80 vol% thereby exhibiting a low wettability
of the conductive paste. When the end portions (12, 12) are immersed into the conductive
paste, upward wetting with the conductive paste is blocked at the border with
the main portion (11) and the external electrode is formed with high dimensional
precision.
