Abstract
A plurality of cell units is stacked. A pressurizing mechanism applies a compressive force in a stacked direction to a stacked structure of the cell units. Each of the cell units includes a power storage cell, and a frame body which supports the power storage cell. The frame body includes a positioning portion which restrains a relative position with respect to a direction perpendicular to the stacked direction of the frame bodies adjacent in the stacked direction. The positioning portion positions the frame bodies with respect to the direction perpendicular to the stacked direction. A margin is kept in a direction in which the frame bodies are closer in the stacked direction in a state where the compressive force is applied to the stacked structure due to pressurization through the pressurizing mechanism.
