Abstract
A hole plug includes a plug main body including a head portion, a leg portion, and a flange portion; and a meltable member annularly covering a periphery of an opening portion, disposed between the flange portion and a panel, and melting when heated to seal between the opening portion and the flange portion. The meltable member includes an annular convex portion at a periphery thereof, which annularly projects in a thickness direction of the meltable member, and abuts against a tip portion of the flange portion when the meltable member thermally shrinks in such a way as to reduce a diameter toward a center of the opening portion.
