NOVELTY - Electric storage component (11) comprises an electrode body (120) having a positive electrode and a negative electrode, a case for housing the electrode body, an insulating component (181) arranged in the case to insulate the electrode body from the case, and a spacer (150, 160, 170) arranged in the case, where spacer is arranged between the insulating component and electrode body. The spacer reduces a space between the electrode body and the case, and suppresses the electrode body from moving in the case.    USE - Electric storage component e.g. lithium-ion secondary battery used as power source of electric car.    ADVANTAGE - Since the spacer is inserted into the case under the condition that it is fixed to the electrode body with the insulating component, the spacer can be smoothly inserted into the case, while the spacer is prevented from being shifted in position in the case. Even when the spacer is a bottom spacer, which is inserted into the case ahead of the electrode body and arranged along the bottom surface of the case, the bottom spacer can be prevented from being shifted in position in the case. The spacer has a round tip end, which comes in contact with the electrode body when it is fixed to the electrode body. Thus, when the spacer is fixed to the electrode body, the electrode body is prevented from being damaged with the tip end of the spacer. The spacer has a round corner part, which comes in contact with the insulating component. Thus, even when the spacer and the insulating component are brought into contact with each other due e.g. to vibration, the insulating component can be prevented from being damaged with the corner part of the spacer.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of electric storage component (11).
