Abstract
Provided is an electric double layer capacitor capable of simply connecting a current collector to an external electrode at a low cost and ensuring a sealing property of a container. The electric double layer capacitor includes: a container in which an opening of a concave portion is sealed; an electrolytic solution and a pair of electrode active materials which are accommodated inside the container; and a pair of conductive films which is respectively and electrically connected to the pair of electrode active materials and is formed from a bottom surface of the concave portion to a surface of the container through an opening edge.

An electrochemical cell comprising:
- a container in which an opening of a concave portion is disposed opposite a bottom surface of the concave portion and is sealed;
- an electrolytic solution and a pair of electrode active materials which are accommodated inside the container;
- and
- a pair of conductive films which is respectively and electrically connected to the pair of electrode active materials and is formed from the bottom surface of the concave portion toward the opening of the container through an opening edge.
