Abstract

A wiring module that is to be mounted on power storage elements having electrode terminals includes a flexible board to be electrically connected to the electrode terminals, a connector connected to the flexible board, and a casing holding the flexible board and the connector. The casing includes a case body to be fixed to the power storage elements, a connector holder holding the connector, and a connection portion that is expandable and retractable and connects the connector holder and the case body such that the connector holder is movable relative to the case body. The flexible board includes a board body section fixed to the case body, and an extra section extending from the board body section and having an end that is connected to the connector. The extra section moves according to expansion and retraction of the connection portion.
