Abstract:
A method for manufacturing a porous metal body according to the present invention includes: a surface oxidizing step of heating a titanium-containing powder in an atmosphere containing oxygen at a temperature of 250° C. or more for 30 minutes or more to provide a surface-oxidized powder; and a sintering step of depositing the surface-oxidized powder in a dry process, and sintering the surface-oxidized powder by heating it in a reduced pressure atmosphere or an inert atmosphere at a temperature of 950° C. or more.
