Document Type and Number:
Japanese Patent JP6658681
Kind Code:
B2
Abstract:
A multilayer inductor manufacturing method includes stacking a first coil conductor layer on a first magnetic layer; stacking a first burn-away material on side surfaces of the first coil conductor layer; stacking a second magnetic layer on the first burn-away material and first magnetic layer; stacking a second burn-away material on the second magnetic layer laterally outside an upper surface of the first coil conductor layer; stacking a second coil conductor layer on the upper surface of the first coil conductor layer and second burn-away material; stacking a third burn-away material on side surfaces and an upper surface of the second coil conductor layer; stacking a third magnetic layer on side surfaces of the third burn-away material and the second magnetic layer; stacking a fourth magnetic layer on the third burn-away material and the third magnetic layer; and burning away the first, second, and third burn-away materials via firing.
