Electric storage device

An electric storage device comprising:

• a first electric storage component including a first positive-electrode mixture layer and a negative-electrode mixture layer opposite to the first positive-electrode mixture layer;
• and
• a second electric storage component that is connected in parallel to the first electric storage component and includes a second positive-electrode mixture layer and a negative-electrode mixture layer opposite to the second positive-electrode mixture layer, wherein
• the positive-electrode mixture layer contains a positive-electrode active material that allows ions to be reversibly doped thereinto and dedoped therefrom,
• the negative-electrode mixture layer contains a negative-electrode active material that allows ions to be reversibly doped thereinto and dedoped therefrom,
• the capacity of the first positive-electrode mixture layer is set higher than the capacity of the second positive-electrode mixture layer, the path resistance of the first electric storage component is set higher than the path resistance of the second electric storage component, and
• a current collector provided between the first positive-electrode mixture layer and the second positive-electrode mixture layer has a through-hole formed therein.
