The window glass 3 may be made of a single sheet of glass or may have a multi-layer structure, and is not particularly limited. When a hard tempered glass having a multilayer structure in which an air layer is formed therebetween and joined in parallel is used, a heat insulating effect is imparted by the air layer, and the outdoor temperature is transmitted to the inner surface side of the window glass 3. And dew condensation is prevented.

The window frame 4 is a rectangular frame body, which is a decorative upper frame 2 for supporting an upper surface of an outer peripheral portion of the window glass 3, and is attached to a lower portion of the upper frame 2, and a lower surface of an outer peripheral portion of the window glass 3. And a wooden lower frame 1 for supporting the same.

The decorative upper frame 2 is an aluminum frame which forms the appearance of the window frame 4 and covers the upper surface and side edges of the outer peripheral portion of the window glass 3. A seal is provided on a support portion of the decorative upper frame 2 that supports the outer periphery of the window glass 3 to ensure waterproofness.

The wooden lower frame 1 has its upper surface joined to the lower portion of the decorative upper frame 2 so as not to be seen from the outdoor side.
A seal is applied to a supporting portion that supports the lower surface of the outer peripheral portion of the rim to ensure waterproofness. Since the wooden lower frame 1 is made of wood, it has low heat conductivity and excellent heat insulation as compared with a metal frame made of aluminum or the like, so that dew condensation hardly occurs on the indoor side surface.

The upper surface of the wooden lower frame 1 is provided with a gutter groove 5 for receiving dew water generated on the lower surface of the window glass 3. As shown in FIG. 3, the gutter grooves 5 are provided so as to communicate with both sides and the water-side side except for the water-side side of the wooden lower frame 1, and are provided on the lower surface of the window glass 3. This is to catch the place where the generated dew condensation water has flowed down the window glass 3 to the lower side. Further, the gutter groove 5 is provided under the gutter groove 5.
