A three-dimensional network porous metallic structure is formed by filling the internal cavity of a mold, which has been prepared by making use of a three-dimensional network resin pattern, through driving the molten metal into the cavity by a pressure or through sucking the molten metal into the cavity by reducing the pressure in the cavity. The porous metallic structure thus obtained is characterized by a large specific surface area, as well as a reduced pressure drop of fluid passing through this structure, and, therefore, is fit for various uses such as the material of fins of heat exchangers, various filters and so forth. |
