A sun visor can appropriately expand its light shielding area without requiring any auxiliary sun visor or the like and hence can be provided at low cost. The sun visor includes a sun visor main body section 101 including a container section 102 having a first width and an aperture section 103 having a second width greater than the first width and held in communication with the container section 102, and a translucent light shielding plate including a light shielding plate main body section 111, a pair of upper projections 112 arranged at the upper lateral ends of the light shielding plate main body section 111 and a pair of lower projections 113 arranged at the lower lateral ends of the light shielding plate main body section, and the width between the pair of upper projections 112 is greater than the second width.
