Title:
LAMINATED COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2012/086397
Kind Code:
A1
Abstract:
Provided is a laminated coil component, wherein film thickness of external electrodes thereof is made to be more uniform. The laminated coil component is provided with: a ceramic laminate comprising a first main face and a second main face, two side faces opposed to each other, and two end faces opposed to each other, and the laminating direction of which is parallel to the first main face and the second main face; a coil conductor built-in within the ceramic laminate; two pull-out electrodes (31, 32) that are electrically connected to the coil conductor, and that have the end sections thereof exposed at the first main face; a plurality of dummy electrodes (41, 42) that have the end sections thereof exposed at the first main face; and external electrodes (21, 22) that are formed on the first main face using an electroplating method, so as to cover the end sections of the pull-out electrodes (31, 32) and the end sections of the dummy electrodes (41, 42). The laminated coil component is characterized in being further provided with connection electrodes (61, 62) for electrically connecting the dummy electrodes (41, 42) and the pull-out electrodes (31, 32) within the ceramic laminate.
