To provide a roll screen device which can be used in a state causing no trouble due to flowing of electric current to a solar cell module which is not irradiated by sunlight.
A roll screen device 1 includes: a winding pipe 30; a support part 40; a pair of main output terminals 51 fixed to the support part 40; a screen 10 where a plurality of solar cell modules 20 are disposed on one surface and one end is connected to the winding pipe 30; and output means (31, 37 etc.) which forms a state where electric current does not flow to respective solar cell modules 20 entirely or partially disposed in unexposed area, wound up by the winding pipe 30, of the screen 10, and synthesizes the outputs of other respective solar cell modules 20 to output it from the pair of main output terminals 51.
