The present invention provides an accumulator device with which, while alleviating short-circuiting, in a positive electrode non-coated part in a positive electrode in which a positive electrode active material is not coated, and a negative electrode coated part in a negative electrode in which a negative electrode active material is coated, ease of fabrication is possible. This accumulator device (10) comprises: positive electrodes (21); negative electrodes (31); separators (19) which are interposed between the positive electrodes and the negative electrodes and insulate both the positive electrodes and the negative electrodes; and an electrode assembly body (18) which is configured by stacking the positive electrodes, the negative electrodes, and the separators. The accumulator device further comprises an insulator member (45) provided with a clamping part (46). The clamping part is formed from a pair of insulation parts which sandwich a positive electrode non-coated part from both sides in the stacking direction of the electrode assembly body. Seen from the stacking direction of the electrode assembly body, each insulation part is positioned at least between a positive electrode boundary and a negative electrode boundary. |
