ROLL-UP CAPACITOR WITH PEROVSKITE DIELECTRIC AND PROCESS FOR PRODUCING THEREOF

摘要

The present invention provides a roll-up type capacitor which comprises a cylindrical part, a first external electrode, and a second external electrode wherein the cylindrical part is obtained by the self rolling-up of a laminate in which a lower electrode layer, a dielectric layer of perovskite type and an upper electrode layer are stacked in this order; the first external electrode is electrically connected to the upper electrode layer, and the second external electrode is electrically connected to the lower electrode layer; and the first external electrode and the second external electrode are respectively located on each of the both sides of the cylindrical part such that they face to each other. The roll-up type capacitor has a low ESR and can be suitably used in a high frequency range.
