CHIP INDUCTOR AND PROCESS FOR PRODUCING THE SAME

摘要

There are provided a chip inductor realizing good Q characteristics while ensuring the feature of thin and small size, and its producing process. The chip inductor (1) is produced by alternately laying a plurality of conductor patterns (31, 32, 33, 34) and insulation layers (35, 36, 37, 38) on a ceramic substrate (2) and forming one coil (30) by connecting the plurality of conductor patterns (31, 32, 33, 34) in series in the laying direction. More specifically, the number of turns of the conductor pattern (31) on the lowermost layer provided directly on the ceramic substrate (2) is set higher than those of the other conductor patterns (32, 33, 34) which are set substantially equally. Preferably, the number of turns of the conductor pattern (31) is set to about 1.5 times that of the other conductor patterns (32, 33, 34).
