PROBLEM TO BE SOLVED: To provide a window structure capable of effectively exhibiting a self-screen action produced by photocatalyst or the like. SOLUTION: A back-up material 7 made of resin foam is fitted to the inside surface of a sash 4, silicone or polysulphide sealing material 8 is disposed between the sash 4 and a window glass 5 through the back-up material 7. In the seal material 8, a seal material 8a part disposed between the lower end outside of the window glass 5 and the sash 4 is different in shape from the other seal material 8 parts. That is, an angleθ2 made between the other sealing material 8 and the surface of the window glass 5 is about 90°similarly to that in the prior art, and an angleθ3 made between the surface of the sealing material 8a and the surface of the window glass 5 is equal to or smaller than 45°. The angleθ3 made up to the window glass is thus made smaller, whereby water flowing along the surface of the window glass 5 does not stay in the part of the sealing material 8a, but smoothly flows down. Accordingly, dirt never stays. COPYRIGHT: (C)2003,JPO
