Abstract:
An electric storage device includes a case, an electrode assembly housed in the case and including a positive electrode plate and a negative electrode plate which are wound together while being isolated from each other, an external terminal arranged outside the case and a current collecting member arranged inside the case to electrically connect the electrode assembly with the external terminal. The current collecting member includes a first portion including a first end portion and a second end portion, and electrically connected to the external terminal, and a second portion extending out of the second end portion of the first portion and electrically connected to the electrode assembly. The second portion includes a base portion including a first end portion and a second end portion, the first end portion of the base portion being connected to the second end portion of the first portion, and a twisted portion.
