PROBLEM TO BE SOLVED: To provide a method for manufacturing an air-permeable metallic material in a low temperature and low pressure condition, and to provide the metallic material having superior air permeability, which can be manufactured in the low temperature and low pressure condition. SOLUTION: The method for obtaining the air-permeable metallic material 7 comprises preparing an SnO<SB>2</SB>powder 1 of an oxide of a low-melting metal, and an Fe powder or a nickel powder 2 which forms an intermetallic compound between itself and the SnO<SB>2</SB>powder 1, mixing the SnO<SB>2</SB>powder 1 with the Fe powder or the Ni powder 2, then molding a mixture of the metal powders to obtain a compact 3 of the metal powders, and further reducing the compact 3 of the metal powders in a reducing atmosphere at a low temperature.
