1. A battery module comprising:
a plurality of batteries stacked together in a stacked direction; and
a separator disposed between an adjoining two of the plurality of batteries and configured to insulate between the adjoining two of the plurality of batteries, wherein
the separator includes a thermal conduction suppressor and a position regulator,
the position regulator defines a through hole extending through the separator in the stacked direction,
the thermal conduction suppressor is disposed inside the through hole of the position regulator when viewed in the stacked direction,
a thickness of the thermal conduction suppressor in an uncompressed state thereof is shorter than a depth of the through hole of the position regulator in the stacked direction,
the thermal conduction suppressor is configured:
to have a lower thermal conductivity than a thermal conductivity of the position regulator; and
to suppress thermal conduction between the adjoining two of the plurality of batteries, and
the position regulator is configured:
to have a greater rigidity than a rigidity of the thermal conduction suppressor;
to abut the adjoining two of the plurality of batteries; and
to regulate a position of each of the adjoining two of the plurality of batteries in the stacked direction.
