PROBLEM TO BE SOLVED: To provide a capacitor-embedded printed circuit board, having a low inductance and a high capacitance. SOLUTION: The capacitor-embedded printed circuit board includes a multilayer polymer capacitor layer 21; at least one first internal electrode 24 and second internal electrode 27 isolated by at least one of a plurality of polymer sheets and paired in an interdigitated arrangement; a plurality of first extraction electrodes 25a and second extraction electrodes 28a connected to the internal electrodes; at least one insulating layer stacked on one or both faces of the multilayer polymer capacitor layer, the at least one insulating layer having a plurality of conductive patterns and conductive via holes formed to constitute interlayer circuits; a plurality of first via holes for a capacitor 26 formed penetrating through the multilayer polymer capacitor layer to be connected with the first extraction electrodes; and a plurality of second via holes for a capacitor 29 formed penetrating through the multilayer polymer capacitor layer to be connected with the second extraction electrodes. The plurality of first and second extraction electrodes are arranged alternately to face each other. COPYRIGHT: (C)2008,JPO&INPIT
