1. An electric storage device, comprising:
an electrode assembly in which electrodes are wound such that paired curved portions and a straight portion connecting the paired curved portions are formed; a case which houses the electrode assembly, the case comprising a convex part only protruding toward the straight portion of the electrode assembly to support the straight portion; a support portion which is in contact with the curved portion and supports the curved portion toward an inside of the electrode assembly; and an insulating member disposed between the case and the electrode assembly to insulate the case from the electrode assembly, wherein the support member is detachably attached to the insulating member, and wherein the support member is configured to be elastically deformed due to contact between the support member and the curved portion.
