Porous material, honeycomb structure, and production method for porous material

A production method for a porous material, having:

• a forming step of extruding a forming raw material containing an aggregate raw material, a composite binding material forming raw material, a pore former and a binder to prepare a formed body;
• and
• a firing step of firing the formed body at 1400 to 1500° C. in an inert atmosphere to produce the porous material,
• wherein the composite binding material forming raw material contains an aluminum oxide component in excess of 34.9 mass % and less than 71.8 mass %, a silicon dioxide component in excess of 28.2 mass % and less than 52.0 mass %, and a magnesium oxide component in excess of 5.0 mass % and less than 13.8 mass %,
• a content of metal silicon in the porous material is smaller than 15 mass %, and
• the composite binding material forming raw material does not contain the metal silicon, or contains such an amount of the metal silicon so that the content of the metal silicon in the obtained porous material is smaller than 15 mass %.
