PROBLEM TO BE SOLVED: To provide a closure member for an opening part excellent in thunder-resistant performance and capable of being manufactured at low cost. SOLUTION: In a door body 30, an outer surface 31a of a plate part 31 is formed by a composite material layer 60, and an inner surface 31b side and a flange part 32 are formed by a metal material layer 61. Further, the door body 30, a clamp ring 40 and an opening part 12 of a wing surface panel 11 are electrically connected to each other on an abutment portion of an abutment surface 34 of the door body 30 and a taper surface 40c of the clamp ring 40 and an abutment portion of a taper surface 40d of the clamp ring 40 and an abutment surface 14 of the opening part 12 by surface-bonding of mutual conductive materials.
