Abstract
Official abstract text for this publication.
A laminated coil component includes an element assembly formed by laminating a plurality of insulation layers and a coil unit formed inside the element assembly by a plurality of coil conductors. The element assembly includes a coil unit arrangement layer which has the coil unit arranged therein, and at least a pair of shape retention layers which is provided to have the coil unit arrangement layer interposed therebetween to retain a shape of the coil unit arrangement layer. The shape retention layer is made from glass-ceramic containing SrO, and a softening point of the coil unit arrangement layer is lower than a softening point or a melting point of the shape retention layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laminated coil component comprising: an element assembly formed by laminating a plurality of insulation layers; and a coil unit formed inside the element assembly by a plurality of coil conductors, wherein the element assembly includes a coil unit arrangement layer which has the coil unit arranged therein, and at least a pair of shape retention layers which is provided to have the coil unit arrangement layer interposed therebetween, wherein the shape retention layer is made from glass-ceramic containing SrO, wherein the coil unit arrangement layer is made from glass-ceramic and contains no SrO, whereby a softening point of the coil unit arrangement layer is lower than a softening point or a melting point of the shape retention layers such that the pair of shape retention layers retain a shape of the coil unit arrangement layer when the element assembly is heated between the softening point of the coil unit arrangement layer and the softening point or the melting point of the shape retention layers, and wherein no conductor is arranged in the shape retention layers. 2. The laminated coil component according to claim 1 , wherein the coil unit arrangement layer contains 86.7 weight % to 92.5 weight % of SiO 2 . 3. The laminated coil component according to claim 1 , wherein the coil unit arrangement layer contains 0.5 weight % to 2.4 weight % of Al 2 O 3 .
