Abstract
To provide an image capturing element and an image capturing apparatus in which an image capturing optical system can be thinned without degrading image capturing properties.An image capturing element according to an embodiment of the present technology includes an on-chip lens, a low refractive index layer and an infrared absorption layer. The on-chip lens is composed of a high refractive index material. The low refractive index layer is formed flatly on the on-chip lens and is composed of a low refractive index material. The infrared absorption layer is laminated above the low refractive index layer and is composed of an infrared absorption material.
