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).
