Abstract
There are disclosed a porous material having a high thermal shock resistance and a honeycomb structure. The porous material contains main aggregates and auxiliary aggregates as aggregates, the main aggregates are silicon carbide particles, the auxiliary aggregates are at least either of mullite particles or alumina particles, the aggregates are bound to one another via a binding phase, so as to form pores, and the binding phase is at least one of an amorphous phase and a cordierite phase, and a porosity is from 40 to 90%. Furthermore, the honeycomb structure is constituted of such a porous material, and includes partition walls defining and forming a plurality of cells extending from one end face to the other end face.
