接着の低下を招くものであった。Conventionally, this type of honeycomb structure is produced by distributing an adhesive, especially an adhesive sheet, between the honeycomb core and the face plate and bonding them together. This has the disadvantage that the adhesive area becomes small and sufficient adhesive strength cannot be obtained. In addition, adhesive sheets are generally made of various woven fabrics,
It has a structure in which a base material made of nonwoven fabric or the like is impregnated with an adhesive resin layer, and when such an adhesive sheet is used, the honeycomb core ( 2
) side adhesive resin layer (3-1) only contributes to adhesion of the honeycomb core, further reducing the adhesion area,
This resulted in a decrease in adhesion.

することによって解決される。Means for Solving Problem C] This problem is solved by using an adhesive sheet made by impregnating a heat-melting (or semi-melting) plastic base material with a thermosetting resin layer, and placing the adhesive sheet between the honeycomb core and the surface plate. This problem can be solved by melting (or semi-melting) the base material of the adhesive sheet by interposing the adhesive sheet and then heating it to bond the honeycomb core and the surface plate.

の大きなハニカム構造物が得られるのである。In the present invention, when a honeycomb core and an adhesive sheet made of a heat-melted (or semi-melted) plastic substrate impregnated with a thermosetting resin layer and a surface plate are laminated and heated under pressure, the second layer is heated. As shown in the figure, the base material (4-3) becomes molten or semi-molten, the viscosity decreases, and further breakage occurs, forming a discontinuous layer. As a result, the honeycomb core passes through the base material layer and the resin layer (4-3) becomes molten or semi-molten.
2) Reach the side. As the heating progresses further, the thermosetting resin layer hardens and adheres, yielding a honeycomb structure with a large adhesive area between the honeycomb core and the surface plate.
