1. A metal-air battery module comprising:
at least one battery-cell row including a plurality of metal-air battery cells connected in series;
a casing housing the plurality of metal-air battery cells;
a plurality of retainers being separate bodies from the casing and the plurality of metal-air battery cells, the plurality of retainers housed in the casing and retaining the plurality of metal-air battery cells; and
a coupler being a separate body from the casing and the plurality of metal-air battery cells, the coupler housed in the casing and coupling the plurality of retainers,
wherein each of the plurality of metal-air battery cells is a two-electrode system-based metal-air battery having a negative-electrode terminal and an air-electrode terminal,
in the at least one battery-cell row, two of the plurality of metal-air battery cells adjacent to each other are arranged in such a manner that the negative-electrode terminal and the air-electrode terminal face each other,
in the two of the plurality of metal-air battery cells adjacent to each other, the negative-electrode terminal of one metal-air battery cell is connected to the air-electrode terminal of the other metal-air battery cell to constitute a pair of connected terminals,
the negative-electrode terminal and the air-electrode terminal of the pair of connected terminals are directly connected,
the plurality of retainers has first cuts for coupling,
the coupler has a plurality of second cuts for coupling, and
the plurality of second cuts for coupling is fitted into the first cuts for coupling to provide a gap between two of the plurality of retainers adjacent to each other.
