PROBLEM TO BE SOLVED: To create comfortable natural environment with the window of a room open while causing the flow of air to facilitate natural exhaust by dividing a window screen into two parts, i.e., an intake port (narrow) and an exhaust port (wide) based on the law of natural science to promote ventilation of the room by dividing the breadth of the window screen heretofore in use, into two large and small parts to open the window (2/3≥1/3) in two left and right parts. SOLUTION: This divided window screen is formed to set the width of a narrow window screen to 1/3 and the width of a wide window screen to 2/3. The intake port and the exhaust port are thereby distinguished to cause the flow of air, which leads to natural ventilation of the room to achieve ventilation. The divided window screens are fastened by a fastener so as to be usable as one in a conventional manner. Fasteners are attached to both sides so as to be usable either right or left according to a service condition. An insect-proof and dust-proof packing is also installed at each window screen.
