PROBLEM TO BE SOLVED: To provide a window shade, for confirming whether or not its slat is inclined as desired even in the case where the inclination of the slat of the window shade cannot be accurately confirmed by visual observation. SOLUTION: An angle display part 40 for displaying an angle of rotation of the slat 18 is provided on the outside of a head box 12. The angle display part is disposed in the head box 12 and operated with rotation of a rotating shaft 22 to which one end of a ladder cord 16 is connected. The angle display part 40 is composed of a moving member 36, both ends of which are connected to a pair of rotors 20 rotated integrally with the rotating shaft 22 within an angle of rotation for rotating the slat, and which is moved in the longitudinal direction of the head box 12 with the rotating direction of the rotor 20, and a fixed mark part 38 indicating the moving position of the moving member 36.
