Abstract
A power storage apparatus has a case accommodating an electrode assembly, and a release valve present in the wall of the case. The electrode assembly includes electrodes. A shielding member is arranged between the inner surface of the wall and the end surface of the electrode assembly. A point located in a center of the case in a front view of the case taken in the stacking direction of the electrodes and located in a center of a dimension of the electrode assembly in the stacking direction is a center point, and a region surrounded by a plane connecting the center point and a contour of the pressure release valve at a shortest distance is a three-dimensional region. The shielding member includes a shielding portion that entirely covers a cross section of the three-dimensional region along the end face of the electrode assembly.
