Abstract:
1. A multilayer electronic component comprising: a ceramic substrate; and a resin layer disposed on one main surface of the ceramic substrate, the resin layer including a main surface arranged to face toward an outside of the multilayer electronic component; wherein the ceramic substrate includes a surface conductive film positioned at at least one of the one main surface and a via conductor; the resin layer includes a columnar conductor made of a sintered metal and arranged such that an axial direction of the columnar conductor lies in a thickness direction of the resin layer, a first end of the columnar conductor in the axial direction reaches at least an interface between the ceramic substrate and the resin layer, the first end of the columnar conductor is integrated with at least one of the surface conductive film and the via conductor provided in the ceramic substrate, and a second end of the columnar conductor opposite to the first end of the columnar conductor protrudes from the main surface of the resin layer such that the second end of the columnar conductor is spaced from the main surface of the resin layer in an axial direction of the columnar conductor.
