摘要:
A chip inductor in which excellent Q characteristic is realized while advantages in its small size and low profile are ensured, as well as a method for manufacturing the same, is provided. A chip inductor 1 is constructed by alternately laminating plural conductor patterns 31, 32, 33, and 34 and plural insulating layers 35, 36, 37, and 38 on and above a ceramic substrate 2, and connecting these plural conductor patterns 31, 32, 33, and 34 to each other in series in the lamination direction thereof so as to constitute a coil 30. Specifically, the number of turns of the lowermost-layer conductor pattern 31 disposed immediately on the ceramic substrate 2 is specified to be larger than the numbers of turns of the other plural conductor patterns 32, 33, and 34, and the numbers of turns of the other plural conductor patterns 32, 33, and 34 are specified to be substantially equal to each other. Preferably, the number of turns of the conductor pattern 31 is specified to be about 1.5 times the numbers of turns of the other plural conductor patterns 32, 33, and 34.
