Abstract:
The electric storage device includes an electrode assembly having a positive electrode and a negative electrode, a case for housing the electrode assembly, a pressure relief valve, and positive and negative electrode conductive members that are electrically connected to the respective corresponding electrodes. The case has a wall in which the pressure relief valve is disposed. At least one of the positive and negative electrode conductive members includes an interposing portion located between the inner surface of the wall and an end face of the electrode assembly facing the inner surface, and a shielding portion located closer to the end face of the electrode assembly than the interposing portion. The shielding portion covers the pressure release valve from a side of the wall where the electrode assembly is located.
