1. An image sensor, comprising:
a substrate including a first surface and a second surface that are opposite to each other; and
a pixel separation part disposed in the substrate, wherein the pixel separation part divides a plurality of unit pixels from each other;
wherein the pixel separation part includes:
a conductive structure that extends from the first surface toward the second surface; and
a first reflective structure disposed between the conductive structure and the substrate,
wherein the first reflective structure includes:
a first reflective liner disposed between the substrate and the conductive structure; and
