1. A metal porous body comprising:
a metal framework;
a separation wall formed in one piece with the metal framework, the separation wall being composed of a same material as a material of the metal framework;
a plurality of cells each having a polyhedral shape exist inside the metal porous body, wherein a side of the polyhedral shape is constituted of the metal framework; and
a closed cell in which an opening of a cell of the plurality of cells is closed by the separation wall exists inside the metal porous body, the opening being defined by a side of the polyhedral shape of adjacent cells among the plurality of cells,
wherein the separation wall is integrally formed with the metal framework so as to completely close the opening, such that the closed cell is non-communicating with the adjacent cells.
