Abstract
A layered product including a plurality of deposition units, each having a thin resin layer and a thin metal layer wherein the surface roughness of the thin resin layer is 0.1 μm or below, a protrusion forming component is not added to the thin resin layer or the surface roughness of the thin metal layer is 0.1 μm or below. The surface characteristics are improved regardless of the thickness of the layered product and the requirement of high performance thin film can be satisfied because the layered product contains no foreign matter. The layered product is suitably applicable to electronic parts, e.g., a capacitor, especially a chip capacitor.
Claims30
A layered product comprising an element layer, reinforcement layers deposited on both sides of the element layer, and protective layers deposited further on both sides of the reinforcement layers,
- wherein the element layer comprises:
- plurality of deposition units, each of which comprises a dielectric layer, a first metal thin film layer and a second metal thin film layer that are deposited on one surface of the dielectric layer and separated by a belt-shaped electrically insulating portion, and are deposited in such a manner that the electrically insulating portions of adjacent deposition units are deposited in different positions;
- and the reinforcement layers comprise:
- a deposition unit that comprises a resin layer, a first metal layer and a second metal layer that are deposited on one surface of the resin layer and separated by belt-shaped electrically insulating band.
