PROBLEM TO BE SOLVED: To suppress dropping of electrostatic capacity and increase of ESR by reducing a thermal stress to a solid electrolytic layer.;SOLUTION: In a solid electrolytic layer 16, a first film layer 16a is laminated on a dielectric layer 14. To or more layers 16d on which such laminate consisting of a grain layer 16b and a second film layer 16c is one unit are laminated on the first film layer 16a.;COPYRIGHT: (C)2007,JPO&INPIT
