A defrosting and heat-insulating device for a window includes a mounting plate part 12 a defining a first opening 12 ah peripherally with four sides of an arbitrary width, assuming a rectangular external shape identical in size with the external shape of a window glass G, and mounted in conjunction with the window glass G on the screen frame F of the glass screen S, a frame part 12 c defining a second opening 12 ch peripherally with four sides of an arbitrary width, disposed in a state laid peripherally on the mounting plate part 12 a on the side thereof opposite the window glass G to protrude outward, and provided with a step 12 ca disposed peripherally on the inner peripheral edge defining the second opening 12 ch, and a plate body 21 mounted on the step 12 ca and adapted to form an air layer a of a prescribed thickness between itself and the window glass G. The device is consequently capable of producing a fully satisfactory defrosting and heat-insulating effect, allowing the mounting work to be simplified and enabling the mounting work to be performed with high workability.
