To facilitate manufacture of a honeycomb core with a plurality of hollow column-shaped cells having open ends on both sides, the open ends on one side being formed into curved surfaces.
A plate base material 27 which is rolled in a roll shape is successively drawn out and cut into a curved line shape with a cutter 29, and the surface on one side of the plate base material 27 is coated with adhesives which are made to stick to an adhesive coating roller 35 as adhesives 33. The plate base material 27 after coated with the adhesives is changed from the horizontal state to a vertical state and cut into a predetermined size, and thus a plate 31 is obtained. A laminate 43 is made by laminating the plurality of cut plates 31 and pressurizing them and adjacent plates 31 are mutually joined and fixed by charging the laminate 43 into a heat treating furnace 45 while it is kept pressurized. After that, the honeycomb core is manufactured by separating unjoined fixed parts other than the joined fixed parts between mutual adjacent plates 31.
