The present disclosure relates to a solid-state imaging element and an electronic apparatus, in which the number of wires controlling readout can be reduced in a case where a pixel signal of each pixel is read out in a predetermined order for each unit pixel region. The unit pixel region is configured by a plurality of pixels arranged in an array. A readout circuit is provided for each unit pixel region and reads out, in a predetermined order, pixel signals of the plurality of pixels configuring the unit pixel regions. Pixel drive wires, which control readout of the pixels configuring the unit pixel regions adjacent in the vertical direction and having the same readout order, are shared. The present disclosure can be applied to, for example, a CMOS image sensor and the like.
