First, as shown in FIGS. 1 (1) and 2 (2), the first bending line B has a long plate-shaped honeycomb sandwich panel 1 along the lateral direction, three in the illustrated example, the longitudinal direction. It is set to be divided at equal intervals and also functions as a cut line. Then, the honeycomb sandwich panel 1 is in a state in which, for each of the first bending lines B as described above, the upper side, that is, the outer skin plate 3 and the honeycomb core 4 are cut into slits, and only the lower side, that is, the inner skin plate 2 is continuous. Leave in. Then, as shown in FIGS. 2 (1) and 2 (2), the honeycomb core 12 on one side of the cut surface is removed by oyster removal by a predetermined length in the direction perpendicular to the cell axis direction. It is crushed by a crush or a crush, so that a cavity 13 is formed between the inner skin plate 2 and the outer skin plate 3 (in FIG. 2 (1), the cavity 13 is formed by crushing). Examples are shown, and in other drawings, the cavity 13 is formed by cutting.
Is shown). The length of such cutting and crushing, that is, the dimension of the cavity 13 in the left-right direction in the drawing is from a minimum of about 1 time the thickness of the honeycomb sandwich panel 1 to, for example, about 3 times. It is set appropriately. That is, the length and depth of the honeycomb core 4 in the cell axis direction, the thickness of the inner skin plate 2, and the thickness of the outer skin plate 3 are set to about 1 to 3 times the total thickness. It The honeycomb core 12 on one side of the cut surface is cut and crushed in this way to form the hollow portion 13, while the honeycomb core 14 on the other side of the cut surface is left unprocessed. .
