Image sensor, for suppressing occurrence of noise components

An imaging apparatus, comprising:

• an image sensor that has a plurality of pixels;
• and
• an image processing portion configured to process an image of a subject obtained by photoelectric conversion in the image sensor,
• wherein each of the plurality of pixels includes:
• a light incident surface;
• a light receiving portion configured to receive light incident on the light incident surface;
• a vertical waveguide between the light incident surface and the light receiving portion, wherein the vertical waveguide is configured to guide the light from the light incident surface to the light receiving portion, wherein the vertical waveguide includes a first end that extends toward the light incident surface and a second end that extends toward the light receiving portion, and wherein a width of a core of the vertical waveguide between the light incident surface and the light receiving portion is uniform;
• and
• a light shielding portion, between the light incident surface and the light receiving portion, configured to block the incident light,
• wherein the light shielding portion includes an opening, wherein the second end of the vertical waveguide extends into the opening,
• wherein the light receiving portion is configured to receive the light that passes via the vertical waveguide and the opening,
• wherein a position of a first center axis of the core of the vertical waveguide is at a specific distance from a position of a second center axis of the opening, and
• wherein the first center axis is in a vertical direction of the vertical waveguide and the second center axis is in the vertical direction of the opening.
