An electric storage device 10 has a first electric storage component 29 and a second electric storage component 30. The first component 29 and the second component 30 are connected in parallel. A positive-electrode mixture layer 22 contains a lithium cobaltate to increase a capacity. A positive-electrode mixture layer 27 contains an activated carbon to increase an output. A current collector 16 having through holes 16a is provided between the layers 22 and 27. A positive electrode terminal 25 is connected to a positive-electrode current collector 21 of the first component 29 through an electricity supply path 24 provided with a resistor 23. By this configuration, the electric current flowing through the first electric storage component 29 can be restricted when the device is charged or discharged with high current.
