An object is to provide a closing member for an opening, the closing member capable of more reliably maintaining a lightning-protective function. In addition to a first insulator (63), a second insulator (65) is provided between a door body (30) and a wing inner surface around an opening. When the first insulator falls off, the second insulator becomes interposed between an inner peripheral planar part and the wing inner surface. With the first insulator being tightly interposed between an outer peripheral planar part and the wing inner surface, the second insulator faces the wing inner surface with a predetermined clearance therebetween. The outer peripheral planar part is formed at a position further away from the wing inner surface than an apical surface of the second insulator mounted on the inner peripheral planar part. The second insulator (65) is formed of a material softer than the first insulator (63). |
