Patent ID: 8367183

Claim:
A honeycomb structure body comprising, A phenol foam sheet ( 1 ) inserted into cell spaces of honeycomb ( 2 ), a gas permeable surface material ( 80 ) and a gas barrier surface material ( 80 ′), wherein the gas permeable surface material ( 80 ) is pressed against tips of walls of the honeycomb cell, whose narrow band area is applied with an emulsion adhesive agent, the phenol foam sheet ( 1 ), which is inserted fully into the cell spaces of honeycomb ( 2 ) to contact with the emulsion adhesive agent applied on the above area, is made of linked cellular structure characterized by a strong water absorbing ability, and the emulsion adhesive agent is hardened enough to make adhesion in limited spots between the gas permeable surface material ( 80 ) and the tips of the wall of the honeycomb cell due to the fact that water contained initially in the emulsion adhesive agent is absorbed by the phenol foam which has the strong water absorbing ability quickly after the phenol foam sheet is inserted to contact with the emulsion adhesive agent.
