<p>[PROBLEMS TO BE SOLVED] To prevent leakage of an interlayer material provided between panels and reduce the time and effort required for sealing gaps. [MEANS FOR SOLVING THE PROBLEMS] A multi-layered panel wherein an interlayer material in a fluid state or in a solidified state transformed therefrom is provided between a pair of panels, comprises an internally-threaded member (30) fitted in a through-hole (16a) formed in an outer one (16) of the panels, and a cap (40) capped on the internally-threaded member (30). The cap (40) has a bottomed tubular-shaped body portion (41) adapted to be brought into close contact with an outer peripheral surface of the internally-threaded member (30) while sealing a threaded hole of the internally-threaded member (30), and a panel-contact contributing portion (42) supported by the body portion (41), and adapted to be, at least partly, closely contactable with the outer panel (16).</p> |
