摘要

An electric storage device (A) includes: an electrode assembly (1) including a positive electrode sheet (7), a negative electrode sheet (8), and a separator (9) for insulating between the electrode sheets; positive and negative current collectors (2 and 3) disposed on both ends of the electrode assembly (1); a case (4) in which the electrode assembly (1) and the current collectors (2 and 3) are housed and that fixes one ends of the positive and negative current collectors (2 and 3); and a support member (13) extending from the positive current collector (2) to the negative current collector (3).
