Abstract
A porous material includes aggregate particles and a binding material. In the aggregate particles, oxide films containing cristobalite are provided on surfaces of particle bodies that are silicon carbide particles or silicon nitride particles. The binding material binds the aggregate particles together in a state where pores are provided therein. The porous material contains at least one of copper, calcium, and nickel as an ancillary component.
