An object of the present invention is to provide a porous body that can be used for various purposes by increasing the surface area while maintaining a high porosity of the porous body made of foam metal. A porous body according to the present invention is a porous body made of a foam metal having a three-dimensional network structure, and a cage-like substance is formed on the surface of the skeleton of the foam metal. The foam metal is preferably Ni, Co or Fe, and the cage-like substance is preferably a carbon nanotube and / or TiO 2 having a photocatalytic function. [Selection] Figure 1 |
