To provide an image sensor whose light receiving ratio can be increased by suppressing the light leaking phenomenon in a manner that the traveling direction of light entering a charge storage part is changed so that the light travels to a photoelectric conversion part.SOLUTION: An image sensor according to the present invention includes a substrate including a first surface and a second surface that face each other, a photoelectric conversion part and a charge storage part that are disposed adjacent to each other in the substrate, a light-blocking pattern disposed on the first surface and overlapping with the charge storage part, and a low refraction pattern provided on the light-blocking pattern.SELECTED DRAWING: Figure 2B 【課題】電荷格納部に入射される光の進行方向を光電変化部に向かうように変化させることによって、光漏り現象を抑制して、受光率を高めることができるイメージセンサーを提供する。【解決手段】本発明によるイメージセンサーは、互いに対向する第１面と第２面を含む基板と、前記基板内に配置され、互いに隣接する光電変換部及び電荷格納部と、前記第１面上に配置され、前記電荷格納部と重畳する遮光パターンと、前記遮光パターン上に提供される低屈折パターンと、を有する。【選択図】 図２Ｂ
