1. A separation recovery method, the method comprising:
supplying a first fluid containing an object to be separated in a first direction from a first principal surface of a metal porous membrane having a plurality of through-holes toward a second principal surface facing the first principal surface so that the first fluid passes through the plurality of through-holes from a side of the first principal surface and the object to be separated is captured on the first principal surface of the metal porous membrane;
after the object to be separated is captured on the first principal surface of the metal porous membrane, supplying a second fluid containing a plurality of particles larger than a size of the plurality of through-holes of the metal porous membrane to the metal porous membrane on which the object to be separated has been captured in a second direction from the second principal surface of the metal porous membrane toward the first principal surface so that the second fluid passes through the plurality of through-holes from a side of the second principal surface; and
capturing the plurality of particles on the second principal surface of the metal porous membrane.
