Title:
LAMINATED INDUCTOR AND LAMINATED INDUCTOR MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/014065
Kind Code:
A1
Abstract:
A laminated inductor (1) includes: a laminate (10); electrodes (15-1, 15-2); connecting conductors (21, 23); and non-magnetic bodies (25, 27). In the laminate (10), a coil (29) is formed spirally while overlapping in a laminated direction in a magnetic body (31). The electrodes (15-1, 15-2) are provided on a bottom surface of the laminate (10). The connecting conductors (21, 23) are disposed so as to penetrate through the laminate (10) from both ends (E1, E2) of the coil (29) toward the bottom surface of the laminate (10) to the electrodes (15-1, 15-2), thereby connecting the ends (E1, E2) of the coil (29) and the electrodes (15-1, 15-2). The periphery of the connecting conductors (21, 23) is covered with the non-magnetic bodies (25, 27). In this way, a loss of the laminated inductor (1) can be decreased.
