A hydrogen containing material comprises a first compound including hydrogen containing material and fluoride, and a second compound including a metal which becomes highly reactive with hydrogen when the metal becomes a compound including fluorine, and a compound including fluorine. The first compound and the second compound are integrally formed into a one-piece layer on the surface of the hydrogen containing material. The metal which becomes highly reactive with hydrogen when the metal becomes a compound including fluorine is at least one metal selected from a rare earth metal, rare earth alloy, Fe, Al, Mg, Ca, Mn, Zn, Zr, Li, or alloys comprising these elements.</PTEXT>
