A roller shade includes a light shielding sheet which can be rolled up in a roll shape, a roller and an electric motor for openably moving the light shielding sheet, guide belts connected to respective lower surfaces of side end parts of the light shielding sheet in a sheet width direction, and a pair of guide parts each having a guide space which receives a corresponding one of the side end parts of the light shielding sheet in the sheet width direction and a corresponding one of the guide belts, for guiding the side end part and the guide belt. In the roller shade, the light shielding sheet is prevented from being creased when the light shielding sheet moves in the width direction while being rolled or unrolled, due to lack of a tension of the light shielding sheet in the width direction.
