Light detection element and electronic apparatus

An electronic apparatus, comprising:

• a light detection element;
• an optical system configured to capture incident light from an object to be detected and form an image on a light detection surface of the light detection element;
• and
• a signal processing circuit configured to perform processing on an output signal from the light detection element,
• wherein the light detection element includes:
• a plurality of photoelectric converters disposed side by side in a matrix form in a semiconductor layer;
• a color splitter layer disposed on a light incident side with respect to the plurality of photoelectric converters and including a low refractive index layer and a plurality of columnar high refractive index portions;
• and
• a plurality of condensers disposed on a light incident side with respect to the color splitter layer and condensing incident light to corresponding high refractive index portions, wherein one condenser in the plurality of condensers is provided for each columnar high refractive index portion in the plurality of columnar high refractive index portions.
