The present disclosure relates to a solid-state imaging element and an electronic apparatus capable of suppressing color mixing and sensitivity reduction in each of pixels of a solid-state imaging element having a vertical spectral structure. A solid-state imaging element according to a first aspect of the present disclosure is a solid-state imaging element including a vertical spectral structure pixel containing a plurality of photoelectric conversion units stacked in layers. The vertical spectral structure pixel includes a first photoelectric conversion unit configured to generate an electric charge in accordance with light having a first wavelength among incident light, a second photoelectric conversion unit configured to generate an electric charge in accordance with light having a second wavelength among the incident light that has been transmitted through the first photoelectric conversion unit, and a first spectral unit formed on an upper surface of the first photoelectric conversion unit and configured to laterally bend a traveling direction of the light having the first wavelength of the incident light. The present disclosure is applicable to an electronic apparatus including an image sensor, for example.
