PROBLEM TO BE SOLVED: To provide a combined sash including an aluminum frame and a resin frame, which is constructed such that most of a contact surface between a window opening and a decorated casing is formed of the resin frame, thereby to further enhance the heat insulating properties and prevent condensation. SOLUTION: According to the combined sash including the aluminum frame 2 mounted in the window opening A and the resin frame 3 covering an indoor- side exposed portion of the aluminum frame 2, the resin frame 3 mounted on the aluminum frame 2 in the window opening A from the internal periphery, is formed of a resin head 31, a resin sill 32, and resin jambs 33 and 34, and these resin head, resin sill, and right and left resin jambs have angle pieces 31d, 41c, 33c, and 34b formed on their indoor portions, respectively. These angle pieces are connected to each other, to thereby form continuous four sides of a resin trim 60. Further, the resin trim 60 makes face contact with the decorated casing 60A of the window opening A.
