A power storage apparatus includes a power storage module having a plurality of power storage elements which are aligned in one direction; a device placed adjacently to the power storage module in the direction of the alignment of the power storage elements; a high-voltage cable used in charge and discharge of the power storage module; and a support structure configured to support the high-voltage cable at a plurality of points to position the high-voltage cable along a reference path. The high-voltage cable is configured to electrically connect an electrode terminal of the power storage module to the device. The electrode terminal is one of two electrode terminals of the power storage module and is located on a farther side of the power storage module from the device.
