PROBLEM TO BE SOLVED: To provide an internal window in which an overhanging frame is rigidly fixed to a decorative frame even if the decorative frame has a step. SOLUTION: The overhanging frame 6 consists of upper, lower, right, and left frame members, and is formed of a base frame 30 fixed to an inside edge of the decorative frame 5 and a cover member 35 covering a room side of each frame member of the base frame. The base frame 30 is formed with: an internal peripheral surface portion 32a which is almost continuous with an internal peripheral surface of the decorative frame 5 and allows an external peripheral surface room side of an internal frame body 2; and a cover member mounting portion 32b on which the cover member 35 is mounted from inside a room. The cover member 35 is formed with: a cover portion 37c which covers an inside surface of the base frame 30; and a fixed portion 37a which is mounted on the cover mounting portion of the base frame. The cover member mounting portion 32b of the base frame and the fixed portion 37a of the cover member have two or more mounting steps 32c, 37b in a depth direction, respectively, and the cover member 35 can adjust its mounting locations on the respective members of the base frame 30 in the depth direction.
