PROBLEM TO BE SOLVED: To provide a connection window capable of ensuring watertightness and airtightness without fail even if windows are mutually connected at different levels. SOLUTION: In this connection window, a plurality of windows storing a window sash or a panel body in a frame body constituted by framing upper and lower frames and right and left vertical frames are horizontally connected through a mullion, and the first window 2 and the second window 3 among the windows are arranged on one side of the mullion 6 and the other side of the mullion 6, respectively. The vertical frame 14 of at least either of the first window 2 and the second window 3 is formed to be shorter than the mullion 6 in the vertical direction. A leveling frame part 15 for extending the vertical frame 14 in the upward and/or downward directions is connected with the vertical frame 14 formed to be shorter than the mullion 6 in the vertical direction. The length of vertical side obtained by adding the length of the leveling frame part 15 is substantially the same as the length of the mullion 6. At least either of the vertical frame 14 of the first window 2 or the vertical frame 24 of the second window 3 is connected with the leveling frame part 15, these vertical frames 14, 24 are mutually connected through the mullion 6, and the first window 2 and the second window 3 are arranged at different levels.
