Abstract: A battery module includes a plurality of cylindrical batteries, a wiring board, a plurality of positive electrode-side current collector members, and a plurality of negative electrode-side current collector members. The wiring board is a wiring board having a multilayer structure in which wiring patterns are formed in a plurality of layers, and includes a positive electrode-side wiring pattern and a negative electrode-side wiring pattern. The respective wiring patterns are formed as different layers of the wiring board. Each positive electrode-side current collector member electrically connects a sealing body functioning as a positive electrode external terminal of each cylindrical battery and the positive electrode-side wiring pattern. Each negative electrode-side current collector member electrically connects a case body functioning as a negative electrode external terminal of each cylindrical battery and the negative electrode-side wiring pattern.

Abstract: An electricity storage module according to the present invention is provided with: a plurality of arranged cylindrical electricity storage devices; and an upper holder which holds the upper end parts of the plurality of electricity storage devices, while being provided with a plurality of containing parts that is formed of a thermoplastic resin. The upper holder comprises an upper support member which is formed of a thermosetting resin and supports electricity storage devices adjacent to each other, while being positioned between the adjacent electricity storage devices. In comparison to the thermoplastic resin, the thermosetting resin is not susceptible to deformation or melting event if heat is applied thereto.
