Abstract: The invention has for its object to provide a titanium oxide-containing paper possessed of satisfactory deodorizing power and well protected against aging of paper, a corrugated board fabricated from the titanium oxide-containing paper, and a deodorizing element constructed using the corrugated board. The titanium oxide-containing paper comprises an ultrafine particulate titanium oxide with an X-ray particle diameter of not larger than 100 nm (T) or a modified ultrafine particulate titanium oxide available on surface-modification of (T) with a metal or a metal compound (T'), at least one inorganic filler (F) selected from the group consisting of sepiolite, silica gel, bentonite, zeolite, magnesium sulfate, asbestos, and active carbon for supporting the titanium oxide (T) or (T'), and an organic fiber material amenable to web formation by papermaking machine. The deodorizing element is constructed by stacking up a multiplicity of units of the above-mentioned corrugated board.
