1. A battery module comprising:
a battery stack having a plurality of batteries stacked, the plurality of batteries each having a top surface provided with an output terminal;
a restraining member that has a flat portion extending along side surfaces of the plurality of batteries in a stacking direction of the plurality of batteries and restrains the plurality of batteries; and
a side separator that has a first portion interposed between each of the plurality of batteries and the flat portion and insulates the plurality of batteries from the flat portion,
the each of the plurality of batteries being disposed with a gap from the first portion,
the side separator includes a protrusion protruding toward the side surface of the plurality of batteries on a surface of the first portion close to the battery stack, and
each battery has a pair of the output terminals on the top surface, and the battery stack and the protrusion overlap in an arrangement direction in which the pair of output terminals are arranged.
