Title:
ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2011/121828
Kind Code:
A1
Abstract:
Disclosed are: an electronic component which is capable of suppressing the generation of magnetic saturation due to magnetic fluxes around coil conductors; and a method for manufacturing the electronic component.
A first insulator layer (19) having a first Ni content is prepared. A coil conductor (18) and a second insulator layer (16) having a first Bi content and a second Ni content that is higher than the first Ni content are formed on the first insulator layer (19). The first insulator layer (19), the coil conductor (18) and the second insulator layer (16) form a first unit layer (17). A laminate (12) is obtained by laminating the first unit layer (17) and an insulator layer (15) for outer packaging. After that, the laminate (12) is fired. After the firing process of the laminate (12), the Ni content in a first portion of the first insulator layer (19), said first portion being sandwiched by the coil conductor (18) from the both sides in the z-axis direction, is lower than the Ni content in a second portion that is the portion other than the first portion in the first insulator layer (19).
