PROBLEM TO BE SOLVED: To provide a method for manufacturing a power storage device, by which generation of foreign matters from an electrode can be suppressed in positioning.SOLUTION: An electrode assembly is manufactured by forming a positive electrode shock absorbing part 27 on a positive electrode 21, and forming a negative electrode shock absorbing part 37 on a negative electrode 31, and letting the positive electrode 21 and the negative electrode 31 fall to a lamination part 55 with the positive electrode shock absorbing part 27 and the negative electrode shock absorbing part 37 down, in which the fall of the positive electrode 21 and the negative electrode 31 is restricted by forcing the shock absorbing parts 27, 37 to abut against a positioning part 59. The positive electrode 21 and the negative electrode 31 are laminated while restricting the movement of the positive electrode 21 and the negative electrode 31 in a widthwise direction of tabs 25, 35 by forcing the tabs 25, 35 to abut against respective tab positioning parts 59a, 59b.SELECTED DRAWING: Figure 7 【課題】位置決め時に電極から異物が発生することを抑制できる蓄電装置の製造方法を提供すること。【解決手段】電極組立体の製造に関し、正極電極２１に正極衝撃吸収部２７を形成し、負極電極３１に負極衝撃吸収部３７を形成した後、正極電極２１及び負極電極３１を正極衝撃吸収部２７及び負極衝撃吸収部３７から積層部５５に落下させる。衝撃吸収部２７，３７を位置決め部５９に当接させて正極電極２１及び負極電極３１の落下を規制し、かつ各タブ２５，３５を各タブ位置決め部５９ａ，５９ｂに当接させてタブ２５，３５の幅方向への正極電極２１及び負極電極３１の移動を規制しながら、正極電極２１と負極電極３１を積層する。【選択図】図７
