NOVELTY - A coin-shaped all solid battery includes a power generating unit including first and second electrodes, and solid electrolyte between the electrodes; a metallic case; a metallic sealing plate; gasket insulating the metallic case from the metallic sealing plate; first conductive layer between the first electrode and the metallic case; and second conductive layer between the second electrode and the metallic sealing plate.    USE - Coin-shaped battery, e.g. alkaline button battery, lithium primary battery, or lithium ion secondary battery is used as power source or backup batteries for portable devices.    ADVANTAGE - The coin-shaped all solid battery is free from risk of electrolyte leakage and has internal resistance lowered as compared with a conventional battery; has improved high rate charge/discharge characteristic and active material utilization ratio as compared with a conventional battery; has alleviated variations in high rate charge/discharge characteristic and active material utilization ratio are as compared with a conventional battery; and has improved in battery life as compared with a conventional battery.    DETAILED DESCRIPTION - Coin-shaped all solid battery includes power generating unit including first and second electrodes (21, 22), and solid electrolyte (23) between the electrodes; a metallic case (25) facing to the first electrode to serve as first electrode terminal; a metallic sealing plate (26) facing to the second electrode to serve as a second electrode terminal; and gasket (27) insulating the metallic case from the metallic sealing plate. A first conductive layer (24a) is interposed between the first electrode and the metallic case to be integrated with the first electrode, and a second conductive layer (24b) interposed between the second electrode and the metallic sealing plate to be integrated with the second electrode. The conductive layer comprises porous metal and the porous metal comprises a molded metal powder.
