Abstract: A titanium material includes a base material made of pure titanium or a titanium alloy; and a carbon layer covering a surface of the base material. The carbon layer includes non-graphitizable carbon, and has an R value (I1350/I1590) of 2.0 or more and 3.5 or less in the Raman spectroscopy using laser having a wavelength of 532 nm. Where I1350 is peak intensity at a wave number of around 1.35×105 m?1 in a Raman spectrum, and I1590 is peak intensity at a wave number of around 1.59×105 m?1 in a Raman spectrum. According to this titanium material, it is possible to realize low contact resistance by the carbon layer. Moreover, this titanium material is not susceptible to surface oxidation and capable of maintaining low contact resistance even when exposed to noble potential.
