Container, Battery or Electric Double Layer Capacitor Using the Same, and Electronic Device

A battery comprising:

• a base body constituted of a side wall and a bottom portion, having a hollow or open portion;
• an electrically conductive layer disposed on a bottom surface of the bottom portion facing the hollow or open portion;
• a first electrode electrically connected to the electrically conductive layer, having a first electrode led-out portion which is led out to an upper surface of the side wall of the base body;
• an electrical storage element housed in the hollow or open portion, composed of a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and an electrolyte;
• and
• a lid body having a second electrode formed on its upper surface, the lid body being bonded to the upper surface of the side wall of the base body in such a manner as to cover the hollow or open portion,
• wherein one of the positive electrode and the negative electrode is electrically connected to the electrically conductive layer, and the other of the positive electrode and the negative electrode is electrically connected to an electrically conductive portion formed on a lower surface of the lid body.

An electric double layer capacitor comprising:

• a base body constituted of a side wall and a bottom portion, having a hollow or open portion;
• an electrically conductive layer disposed on a bottom surface of the bottom portion which bottom surface faces the hollow or open portion;
• a first electrode electrically connected to the electrically conductive layer, having a first electrode led-out portion which is led out to the upper surface of the side wall of the base body;
• an electrical storage element housed in the hollow or open portion, composed of a first polarizable electrode, a second polarizable electrode, a separator interposed between the first polarizable electrode and the second polarizable electrode, and an electrolyte;
• and
• a lid body having a second electrode formed on its upper surface, the lid body being bonded to the upper surface of the side wall of the base body in such a manner as to cover the hollow or open portion,
• wherein one of the first polarizable electrode and the second polarizable electrode is electrically connected to the electrically conductive layer, and the other of the first polarizable electrode and the second polarizable electrode is electrically connected to an electrically conductive portion formed on a lower surface of the lid body.
