PROBLEM TO BE SOLVED: To provide a sun visor capable of securing a visual field of a user as much as possible while achieving the purpose of light shielding.SOLUTION: A sun visor includes a first light control part 40F and a second light control part 40B. The first light control part 40F and the second light control part 40B are both configured by a polarizing film in which a region A1 in which a polarization axis becomes a first direction pa1 and a region A2 in which the polarization axis becomes a second direction pa2 are formed alternately. Out of the polarizing film, by deviating the positions which become the first light control part 40F and the second light control part 40B respectively, transmissivity of the second light control part 40B with respect to the light transmitted through the first light control part 40F is adjusted.

    【課題】遮光の目的を果たしつつもユーザの視界を極力確保することのできるサンバイザーを提供する。【解決手段】サンバイザーは、第1光制御部40Fおよび第2光制御部40Bを備える。第1光制御部40Fおよび第2光制御部40Bは、いずれも、偏光軸が第1方向pa1となる領域A1と、偏光軸が第2方向pa2となる領域A2とが交互に形成された偏光フィルムによって構成される。偏光フィルムのうち、第1光制御部40Fと第2光制御部40Bのそれぞれとなる位置をずらすことで、第1光制御部40Fを透過した光に対する第2光制御部40Bの透過率を調整する。【選択図】図3
