The present technology relates to an imaging element, an electronic device, and a manufacturing method that make it possible to prevent color mixing in a pixel adjacent to a phase difference detection pixel and to make the light receiving sensitivity high or more. An anti-reflection film is formed only on the side wall of a light blocking unit that blocks part of the incident light on a photo diode of phase difference detection pixels for detecting the phase difference out of a plurality of pixels. Thereby, the light reflected at the side wall of the light blocking unit does not enter a photo diode of an adjacent pixel, and therefore color mixing is prevented. Furthermore, since the anti-reflection film is not formed on an interlayer layer, the light receiving sensitivity of the light that directly enters the photo diode is not reduced. The present technology can be applied to imaging elements.
