Abstract:
An electric storage apparatus includes a plurality of electric storage elements placed side by side along a predetermined direction and a restraint plate placed between two of the electric storage elements adjacent to each other in the predetermined direction. The electric storage element has a power-generating element performing charge and discharge and a case housing the power-generating element. The restraint plate has protruding portions which give a restraint force to the electric storage element and form a space between the restraint plate and the electric storage element. The power-generating element has a positive electrode plate, a negative electrode plate, and a separator placed between the positive electrode plate and the negative electrode plate. The power-generating element includes a reaction area where a chemical reaction associated with the charge and discharge occurs. The plurality of protruding portions have a first protruding portion in contact with a first area in the case and a second protruding portion in contact with a second area in the case. The first area in the case is opposite to the reaction area, and the second area in the case is opposite to the area of the power-generating element except the reaction area.
