摘要：
According to the present invention, a porous material is characterized by comprising: a connected structure formed by combining silicon carbide which is an aggregate with cordierite which is a combining material in a state to hold a large number of pores, and having a porosity of 52 to 70% and a median pore diameter of 15 to 30 μm, and is a porous material having a high porosity and a high strength and having a remarkably low possibility of including defective portions such as cuts and the like causing liquid leakage in a case where the material is used as a filter.
