The present technology relates to a battery module and a manufacturing method thereof. This battery module (100) is provided with: a plurality of battery cells (11) arranged side by side in a first direction and each having a rectangular shape; and two restraining members (43) that are provided so as to be aligned in a second direction orthogonal to the first direction with respect to the plurality of battery cells (11), and that restrain the plurality of battery cells (11) in the first direction. The two restraining members (43) include a plate-shaped portion (431) extending in a plane direction including a third direction orthogonal to the first direction and the second direction and the first direction. The plate-like portion (431) is formed of a metal member (430A) having an embossed pattern along the third direction, and an opening (432) is provided in the plate-like portion (431). 本技术涉及电池模块及其制造方法。本发明的电池模块(100)具备：多个电池单元(11)，在第1方向上排列配置，并分别具有方形形状；和两个约束部件(43)，设置为相对于多个电池单元(11)在与第1方向正交的第2方向上排列，并沿着第1方向约束多个电池单元
