Abstract: Provided is a door weather strip that provides excellent closing performance of a door and sound insulation properties, and does not impair the appearance. A door weather strip includes a mounting base and a hollow seal portion. The mounting base has a hole penetrating the mounting base, and the hole is mounted with a valve penetrating the mounting base. At the time of manufacturing a vehicle, the door is closed with the valve open, so that the air within the hollow seal portion is discharged to compress and shape the hollow seal portion (first step). When the door is opened, the valve is closed to retain the shaped state of the hollow seal portion (second step). The valve is opened again at a time point when the hollow seal portion begins to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed (third step).
