PURPOSE: A sensor-attached sheet for drying bedclothes is provided to easily perceive the status of wetness and dryness on bedclothes without contacting it, so that its dryness is always maintained. CONSTITUTION: The sensor-attached sheet comprises a sensor(2), a hygroscopic cloth sheet (1), and a transparent sheet(3). The sensor(2) is closely attached on the hygroscopic cloth sheet(1), wherein the sensor is a substance of which color is changeable when it becomes wet and it return to the origin color when it becomes dry, which enables to repeatedly reuse it. The hygroscopic cloth consists of polyester 2D treated with a hydrophilic detergent and viscos rayon 1.5D having the strong hygroscopic power. The sensor is covered with a water-permeable transparent sheet(3). The fore mentioned sheet allows to fast remove the water in a sheet, so that insects, for example a tick, cannot live in the sheet.
