Title: Laminated chip inductor and manufacture thereof
Inventor: NAKAZAWA CHIKASHI
IPC: H01F41/04
Filed: 1990-09-20
Abstract: PURPOSE:To reduce a fluctuation in a value L due to the effect of a magnetic field by a method wherein a magnetic material sheet is peeled from conductor patterns in all the boundaries between the magnetic material sheet and the conductor patterns or in one part of the boundaries. CONSTITUTION:In this laminated chip inductor, a magnetic material sheet 12 is peeled from conductor patterns 14, a conductor pattern 14a and a conductor pattern 14b in all the boundaries between the sheet 12 and the patterns 14, 14a and 14b or in one part of the boundaries and cavities 18 are formed. Thereby, when the sheet 12 is made to expand or shrink by a magnetic field, the sheet 12 and the patterns 14, 14a and 14b do not exert a stress on each other. In the manufacturing method of this inductor, the firing shrinkage amounts of the patterns 14, 14a and 14b are made larger than the firing shrinkage amount of the sheet 12. Accordingly, at the time of firing, this sheet is peeled from the patterns in all the boundaries between the sheet and the patterns or in one part of the boundaries. In this inductor, it is desirable that the specific surface area of magnetic material powder, which is the raw material for the sheet, is set into an area of 1.0 to 10.0m<2>/g and the specific surface area of conductor powder, which is the raw material for the patterns, is set into an area of 0.5 to 5.0m<2>/g.
