A titanium material for a solid polymer fuel cell separator having a low contact resistance and a method of production of the same, the titanium material having at its surface a surface layer structure in which particles of a Ti compound containing either C or N are dispersed, the particles of Ti compound being covered by titanium oxide and/or metal Ti, characterized in that, when analyzed from the surface by XPS, a T12p spectrum of TiO2 is detected, further, at a Ti2p spectral energy range of TiO and/or a Ti2p spectral energy range of metal Ti, a Ti maximum detection peak height is at least 3 times the standard deviations of the background at the respective spectral energy ranges, and at a C1s spectral energy range and N1s spectral energy range, a maximum detection peak height is less than 3 times the standard deviations of the background at the respective spectral energy ranges of C1s and N1s, are provided. |
