NOVELTY - The device i.e. coin-type battery (1), has a separator (14) positioned between a positive electrode (13) and a negative electrode (16). A visible outline appears when an electrically conductive adhesion layer is projected on a virtual surface perpendicular to joining direction of the electrically conductive adhesion layer and the negative electrode. The negative electrode collector is a sealing board (15). The electrically conductive adhesion layer is a positive electrode side electrically conductive adhesion layer (12) and a negative electrode side electrically conductive adhesion layer (17).    USE - Electrical storage device i.e. coin-type battery, for providing uninterruptible power supply for a portable electronic device e.g. electric tool, vacuum cleaner, robot, mobile telephone, mobile device, portable information terminal i.e. personal digital assistant, notebook-type personal computer, video camera and game machine, to facilitate electric power leveling with power generation equipment e.g. wind power generation equipment and fuel cell power generation equipment in a general household, emergency electrical storage system for apartment, and an off-peak electric power electrical storage system. Can also be used as a primary battery, secondary battery, electrolytic capacitor, sensor, and an electrochromic element.    ADVANTAGE - The visible outline appears when an electrically conductive adhesion layer is projected on a virtual surface perpendicular to joining direction of the electrically conductive adhesion layer and the negative electrode such that the electrically conductive adhesion layer is settled inside external shape of the electrodes and not protruded from the external shape of the electrode, so that adhesion with the electrically conductive adhesion layer and the separator does not arise, thus reducing production of performance variation and generation of performance defect, and providing a stable device that has better large-current-discharge characteristic, and hence ensuring adhesiveness and electroconductivity of the electrodes and the collector by the electrically conductive adhesion layer and reducing internal resistance.
