Abstract: A window assembly has a window pane formed from inorganic glass and a concealing member formed along a peripheral edge of the window pane. The concealing member is bonded to the window pane through an adhesive layer containing an acid-modified polyolefin resin or an acid-modified olefin-styrene copolymer resin as a main component. The concealing member is formed in such a manner that a forming material mainly containing an olefin-based thermoplastic elastomer material or a styrene-based thermoplastic elastomer material is heated and molten, and the molten forming material is brought into pressure contact with the window pane having the adhesive layer formed thereon in advance, and then cooled and solidified.
