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: An electronic-component manufacturing method is for simultaneously manufacturing a plurality of electronic components each including an element body and a conductor. The electronic-component manufacturing method includes the steps of forming laminates to be the plurality of electronic components on a plurality of regions set apart from each other on a surface of a first substrate, releasing the laminates from the plurality of regions, and performing heat treatment to the laminates. The forming the laminates includes a first step of forming element-body patterns on the plurality of regions and a second step of forming conductor patterns on the plurality of regions. The element-body patterns contain a constituent material of the element bodies and are patterned for the plurality of regions. The conductor patterns contain a constituent material of the conductors and are patterned for the plurality of regions.
