The present invention aims to provide an electric storage apparatus configured to prevent external terminals of adjacent electric storage devices from contacting each other, even if a compressive force in a direction in which a plurality of electric storage devices are aligned acts thereon. In the electric storage apparatus of the present invention, a spacer is arranged between each adjacent two of the plurality of electric storage devices having external terminals, and a portion opposite to the external terminal side of the spacer has a lower rigidity than a portion on the external terminal side of the spacer.
