PURPOSE:To enhance the mutual bonding strength of sheets at baking temp. of 400-700 deg.C, by bonding the mutual contact parts of corrugated heat resistant sheets or the contact parts of the corrugated heat resistant sheet and a flat heat resistant sheets by titanium oxide sulfate. CONSTITUTION:A plurality of corrugated heat resistance sheets A or the sheets A and flat plate shaped heat resistant sheets B are alternately laminated to produce a honeycomb structural body. In this case, at least the mutual contacts parts of the sheets A or the contact parts of the sheets A and the sheets B are bonded by titanium oxide sulfate. When a honeycomb structural body having a thin wall thickness is prepared, the thickness of each of the sheets A, B is pref. about 0.4-1.5mm. Titanium oxide sulfate functioning as a binder is a crystal substance having a molecular formula TiSO4.nH2O (n is 1.8-2.2) and is soluble in water.
