A porous material includes aggregates, and a bonding material bonding between the aggregates and including cordierite as a main component, and surfaces of three-phase interfaces in which the aggregates, the bonding material and pores intersect are smoothly bonded. Furthermore, in the porous material, the bonding material may include at least one additive component selected from the group consisting of strontium, yttrium, and zirconium, and a bending strength of the porous material is 5.5 MPa or more, or a honeycomb bending strength of a honeycomb structure using the porous material may be 4.0 MPa or more. |
