An airtight test method is provided. The method includes the following steps. First, an opening structure is provided, wherein the opening structure is formed on a building structure. A seal structure is subsequently pressed against the corresponding opening structure, wherein the opening structure and the seal structure compose a chamber. Next, a pressure supply unit is connected to the chamber. A pressure difference is subsequently generated in the chamber by the pressure supply unit. Finally, a measured flow rate between the pressure supply unit and the chamber is detected to measure the airtightness of the opening structure.
