To provide a porous titanium sheet small in contact resistance with a separator with respect to the porous titanium sheet to be used for a conductive porous metal of a solid polymer fuel cell, and to provide a method for manufacturing the porous titanium sheet.
In the porous titanium sheet having small contact resistance and the method for producing the porous titanium sheet, a water-repellent material layer 9 is formed on a foam titanium sheet consisting of continuous holes 1 that open on the outer surface and continue to inner holes and a skeleton 2, a part of the distal end of each projecting part 4 is ground to remove the water-repellent material layer 9, and an Au layer 5 is formed only on a ground surface.
