Abstract:
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.
