Abstract
An imaging device is provided to inhibit deterioration in imaging performance due to high-angle incident light. The imaging device includes a semiconductor substrate including a plurality of photoelectric conversion elements. The imaging device includes a plurality of color filters on the semiconductor substrate that face each of the plurality of photoelectric conversion elements. The imaging device further includes a partition wall on the semiconductor substrate that provides separation between one color filter and another color filter adjacent to each other among the plurality of color filters. The partition wall includes a first metal layer, a translucent first partition wall layer that covers a side surface of the first metal layer, and a translucent second partition wall layer located between the first metal layer and the first partition wall layer. A refractive index of the second partition wall layer is larger than a refractive index of the first partition wall layer.
