An image sensor includes a substrate including a sensor array area, a pad area, and a circuit area, a wiring layer on the pad area, and a light-shielding pattern on the sensor array area. The sensor array area includes a first area including active pixels and a second area including optical back pixels. The wiring layer is apart from the substrate by a first distance on the pad area. The light-shielding pattern includes a first portion spaced apart from the substrate by a second distance less than the first distance, a second portion disposed between the first portion and the wiring layer and extending on the same level as the wiring layer, and a third portion disposed between the first portion and the second portion and integrally formed with the first portion and the second portion.

Image sensor including planar boundary between optical black and active pixel sensor areas with a wiring layer comprising a stepped portion and a via contact portion that penetrates through the pad area of a substrate
