ABSTRACT:
An electric storage device10has a first electric storage component29and a second electric storage component30. The first component29and the second component30are connected in parallel. A positive-electrode mixture layer22contains a lithium cobaltate to increase a capacity. A positive-electrode mixture layer27contains an activated carbon to increase an output. A current collector16having through holes16ais provided between the layers22and27. A positive electrode terminal25is connected to a positive-electrode current collector21of the first component29through an electricity supply path24provided with a resistor23. By this configuration, the electric current flowing through the first electric storage component29can be restricted when the device is charged or discharged with high current.
