The invention relates to a container for electric energy storage device excellent in the manufacturing efficiency and easy for surface mounting to an external electric circuit board, and a battery and electric double layer capacitor at high performance using the same. A container for electric energy storage device includes a frame (1), a first sealing member (2) bonded to the frame (1) so as to close a first opening of the frame (1), and a second sealing member bonded to the frame (1) so as to close a second opening of the frame (1) and having a connection end portion disposed side by side with the first sealing member (2). The container for electric energy storage device can be manufactured through a simple manufacturing process and can be surface-mounted easily.
