Abstract

A battery module according to an embodiment of the present disclosure includes: a battery cell stack in which a plurality of battery cells are stacked; a module frame accommodating the battery cell stack and having an open upper part; and an upper plate covering the battery cell stack over the open upper part of the module frame. The module frame includes a bottom part and two side parts opposite to each other. The bottom part of the module frame includes a first region and a second region, the first region being located along an edge of the bottom part extending along at least one of the side parts of the module frame, and the second region being located inside the first region. The thickness of the bottom part of the module frame is smaller in the second region than in the first region.
