PROBLEM TO BE SOLVED: To prevent the penetration of a resin into the cells of a honeycomb structure while ensuring the weight reduction using the honeycomb structure. SOLUTION: A thermoplastic film 5, a heated honeycomb structure 1, the thermoplastic film 5 and a caul 21 provided with grooves 23 and 25 are successively stacked on a receiving stand 15 having grooves 17 and 19 provided on the surface thereof. The honeycomb structure 1 having the thermoplastic films 5 arranged on both sides thereof is pressurized between the receiving stand 15 and the caul 21. The thermoplastic films 5 are melted at their regions pressed between the regions, which have no grooves 17 and 19 as well as 23 and 25 of the receiving stand 15 and the caul 21, and the honeycomb structure 1 under heating to be welded to the honeycomb structure 1. On the other hand, since the thermoplastic films 5 are not sufficiently brought into contact with the honeycomb structure 1 at the regions corresponding to the grooves 17 and 19 as well as 23 and 25 respectively provided to the receiving stand 15 and the caul 21 thereof even if pressed, those regions of the thermoplastic films 5 become non-welded parts without being melted and the thermoplastic films 5 are brought to a connected state by the non-welded parts without being mutually divided between cells 3.
