Abstract
An aircraft of the present invention includes an outer panel 4 made of a fiber reinforced plastic material, a support member 5, and a lightning protection fastener 1. The fastener 1 includes a metal fastener body 2 having a shaft portion 10 and a head portion 20, and an insulating member 30 made of an insulating plastic material and mounted to the head portion 20. The portion 20 has a frustoconical-shaped fastener seat surface 211. The panel 4 includes a receiving surface 41 conforming to the fastener seat surface 211. The member 30 includes an insulating seat surface 321 retracted from a plane of the fastener seat surface 211 such that, when a portion 41A of the receiving surface 41 which is opposed to the fastener seat surface 211 is depressed, an insulating seat surface 321 comes into contact with the receiving surface 41.
