A titanium material including a base metal made of pure titanium or a titanium alloy and a titanium oxide film formed on the base metal. Peak intensities obtained by thin-film X-ray diffraction analysis performed on an outer layer of the titanium material using an incident angle of 0.3&#xb0; satisfy (I(104)+I(200))/I(101)&#x2265;0.08&#x2212;0.004&#xd7;I(200), where I(104) is the peak intensity resulting from a plane (104) of a TiOphase, I(200) is the peak intensity resulting from a plane (200) of a TiO phase, I(101) is the peak intensity resulting from a plane (101) of an &#x3b1;-Ti phase, and 0&#x3c;I(104), 0&#x2264;I(200), and 0&#x3c;I(101). The titanium material is inexpensive and has both the electrical conductivity and corrosion resistance.
