摘要: A panel (1) has a layered structure including: a first outer layer (2), an intermediate layer (3), and a second outer layer (4). The second outer layer (4) has a buckling stress lower than a buckling stress of the first outer layer (2), and the first outer layer (2) and the second outer layer (4) each have a compression failure stress higher than the buckling stress of the second outer layer (4).
