Abstract
An electric double layer capacitor includes: a cell which includes a pair of polarizable electrodes impregnated with an electrolytic solution and disposed in opposed relation with a separator interposed therebetween; collector electrodes respectively attached to the polarizable electrodes; and a sealing member of a synthetic resin which seals a periphery of the cell. The collector electrodes extend outward of the sealing member through the sealing member in contact with the sealing member. The collector electrodes each have a rough surface portion which extends through the sealing member.

An electric double layer capacitor comprising:
- a cell which includes a pair of polarizable electrodes impregnated with an electrolytic solution and disposed in opposed relation with a separator interposed therebetween;
- collector electrodes respectively attached to the polarizable electrodes;
- and
- a sealing member of a synthetic resin which seals a periphery of the cell,
- wherein the the sealing member consists of two half bodies joined to each other, the half bodies being coupled integrally with the collector electrodes by burying a portion thereof,
- the collector electrodes extending outwardly from the cell through the half bodies in the opposite direction each other,
- wherein the collector electrodes each have a rough surface portion at a portion extending through the half bodies.
