Abstract
The present invention aims to provide a circuit module that includes a sheet-like solid electrolytic capacitor and reduces an area and volume required for mounting electronic components. In the sheet-like solid electrolytic capacitor, valve metal sheet 11 has dielectric layer 13 and current collector layer 12 formed on the surface thereof, and is packaged by insulators 14 and 15. The circuit module is structured to embed the sheet-like solid electrolytic capacitor in a circuit board.
Claims20
A circuit module incorporating a sheet-like solid electrolytic capacitor into a circuit board, wherein said sheet-like solid electrolytic capacitor comprises a valve metal sheet body having a porous surface on at least a part of one side thereof, a dielectric layer formed on the porous surface, a solid electrolyte covering said dielectric layer, and a current collector layer formed on a surface of said solid electrolyte.
