PROBLEM TO BE SOLVED: To provide the mounting structure of a handle for a sash in which dew-proof performance and heat insulation properties can be improved when the handle is installed on the window frame side of the operator handle or the like. SOLUTION: A handle mounting member 40 made of a resin is fixed onto the indoor member 22 of a lower frame 20, and the operator handle 80 is mounted on the handle mounting member 40. Since the handle mounting member 40, to which the operator handle 80 is set up, is formed of the resin having excellent heat insulation properties, the generation of dew condensation in the section of the member 40 can be inhibited, and dew-proof performance and heat insulation properties in a window frame 2 can be further improved.
