PROBLEM TO BE SOLVED: To facilitate the formation of a window frame by eliminating the need for repairs of a cutout portion formed at the rail of its bottom frame. SOLUTION: This window frame includes a cutout portion 3a for draining at the rail 3 of its bottom frame 2 constituted of color aluminum sash, and a cap 6 attached so as to be capable of covering the whole inner periphery of the cutout portion 3a from above the cutout portions 3a. Attaching the cap 6 eliminates the removal of burrs generated at the formation of the cutout portion 3a and the shielding of an aluminum skin exposed at the inner periphery of the cutout portion 3a. It is thus possible to facilitate the formation of the window frame.
