PROBLEM TO BE SOLVED: To provide a solid-state imaging element capable of enhancing the detection precision by suppressing crosstalk. SOLUTION: In the solid-state imaging element 11 having a group of imaging pixels 12 which are provided in an imaging surface and generate pixel signals by photoelectric conversion of received luminous fluxes per pixel, a pixel 13 for focus detection is provided which generates a signal for focus detection by pupil-dividing and photoelectric conversion of the received luminous fluxes per pixel, and the pixel 13 for focus detection has a fist charge storage part 18a and a second charge storage part 18b, and a first charge absorption part 17a is provided between the first charge storage part 18a and a wiring layer 16, and a second charge absorption part 17b is provided between the second charge storage part 18b and the wiring layer 16, and the first charge storage part 18a and the first charge absorption part 17a are electrically connected, and the second charge storage part 18b and the second charge absorption part 17b are electrically connected.
