Abstract
A porous body includes skeleton particles directly binding with each other and forming inner surfaces and void spaces, each of the skeleton particles being one of a nitride ceramic, a carbide ceramic and an oxide ceramic, and inorganic compound components bound to the inner surfaces formed by the skeleton particles directly bound with each other and including an inorganic compound formed by calcinating pore forming particles including an organic polymer and inorganic particles being one or more inorganic material of a nitride ceramic, a carbide ceramic, an oxide ceramic, a metal and a metal compound. The ceramic of the skeleton particles is different from the inorganic compound of the inorganic compound components.
