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.
