TITANIUM-BASED POROUS BODY AND METHOD OF PRODUCING THE SAME

To provide a titanium-based porous body that has high void fraction to ensure gas permeability and water permeability for practical use as an electrode and a filter, has a large specific surface area to ensure conductivity and sufficient reaction sites with a reaction solution or a reaction gas, thus showing excellent reaction efficiency, and contains less contaminants because of no organic substance used. A titanium-based porous body having a specific void fraction and a high specific surface area is obtained by filling an irregular-shaped titanium powder having an average particle size of 10 to 50 μm in a dry system without using any binder or the like into a thickness of 4.0×10to 1.6 mm, and sintering the irregular-shaped titanium powder at 800 to 1100° C.
