At least one of the plurality of plates may comprise a plurality of holes which are configured to function as liquid channels. The plate may comprise a plurality of individual bonding margins which are formed on a surface of the plate, and individually surround the plurality of holes. The plate may comprise a bonding margin bridge which extends parallel to a direction connecting the plurality of holes to each other, and connect the plurality of individual bonding margins to each other. The plate may comprise a groove which defines outer edges of the plurality of individual bonding margins and the bonding margin bridge on the surface of the plate.
