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.
