<P>PROBLEM TO BE SOLVED: To provide a porous titanium, at least on whose skeleton surface Au particles or Pt particles are fixed and whose contact resistance is small and will not increase, even if it has been left standing over a long period, in a vibration environment and corrosive environment. <P>SOLUTION: At least on the external surface of the skeleton 2 of the porous titanium composed of continuous voids 1, which open at the surface and continue to internal voids, particles 5 comprising Au or Pt are dispersed and fixed. In the spaces in between the particles 5 of Au or Pt fixed at least on the skeleton external surface 4, a composite oxide layer 8 is formed which is obtained, by laminating on a titanium oxide layer 3 a silicon oxide-containing oxide layer 7 comprising a silicon oxide layer, a mixed oxide layer of silicon oxide and titanium oxide, a mixed oxide layer of silicon oxide and aluminum oxide, or a mixed oxide layer of silicon oxide, titanium oxide and aluminum oxide. <P>COPYRIGHT: (C)2008,JPO&INPIT |
