Title:
ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2007/125724
Kind Code:
A1
Abstract:
Provided is an electronic component wherein corrosion does not easily advance
due to entry or the like of moisture from an electrode pattern which extends to
the inner side of a substrate main plane from an end formed by a substrate side plane
and one main plane, and characteristics are not easily deteriorated with time.
In an electronic component (1), an electrode is formed on a first main plane (2a).
The electrode is provided with a first electrode pattern (3) which extends to
the inner side of a first main plane from an end formed by the side plane (2c) of a
substrate (2) and the first main plane (2a); a second electrode pattern (4) facing
an end section (3a) of the first electrode pattern (3) by having a gap (G) in between;
and a third electrode pattern (5), which covers the gap (G) and reaches the upper
surfaces of the first and the second electrode patterns (3, 4). A third electrode
pattern (5) is composed of a metal film having higher corrosion resistance than
that of metal films constituting the first and the second electrode patterns
(3, 4).
