Title:
CAPACITOR
Document Type and Number:
Japanese Patent JP2010021234
Kind Code:
A
Abstract:

To provide a capacitor which reduces the ESR (equivalent series resistance).

The capacitor is provided with (a) a pair of electrode layers 15 and 17, (b) a dielectric layer 16 disposed between a pair of the electrode layers 15 and 17 and (c) a pair of lead out electrodes 30s and 32; 30t and 34 connected to a pair of the electrode layers 15 and 17. One electrode layer 15 has (i) a center part 15p, overlapping a capacity-generating part, where a pair of the electrode layers 15 and 17 confront each other through the dielectric layer 16, when it is viewed via from a direction, where the electrode layers 15 and 17 and the dielectric layer 16 are laminated and (ii) a periphery part 15q, which extends outward from the center part and continuously surrounds the center part over the whole circumference. One extraction electrode 30s is connected to a periphery part 15s of one electrode layer 15 at one part, and a connection face continuously surrounds the center part 15p over the entire circumference.
