A window frame(1) comprises a main frame(10) coupled to an opening of a wall section, a plurality of division frames(20) installed in the main frame, a frame coupling member for coupling the division frames to each other at cross points between the division frames, and an indoor-side finishing member for finishing an indoor side of the division frames. The main frame has a thickness identical to a thickness of the wall section. The main frame is coupled with the opening of the wall section such that front and rear surfaces thereof are aligned in line with the indoor and outdoor sides of the wall section. |
