A hole plug comprising: a main body part including a cover flange portion for covering an opening, an insertion portion extended from a central portion of a back surface of the cover flange portion to be inserted into the opening, and an engaging portion formed on an outer periphery of the insertion portion to be engaged with a back side peripheral edge of the opening; a thermo-softening resin member mounted on a peripheral edge of the cover flange portion and allowed to flow into a clearance between the cover flange portion and an opening peripheral edge of the plate-shaped member, thereby fixing them together; and an elastic flange portion extended in a skirt-like manner from the back surface of the cover flange portion toward the peripheral edge of the opening and elastically contactable with the peripheral edge of the opening of the plate-shaped member.
