Abstract: A laminated electronic component includes an element body and a pair of conductors. The element body is formed by laminating a plurality of element-body layers in a first direction. The pair of conductors is formed by laminating a plurality of conductor layers in the first direction. The pair of conductors is provided to the element body in such a way as to be separated from each other in a second direction orthogonal to the first direction. At a cross section orthogonal to the first direction, the pair of conductors has an uneven portion and the element body has an uneven portion engaged with the uneven portion of the pair of conductors.

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.
