The present disclosure relates to a solid-state imaging element and electronic equipment that make it possible to sufficiently secure a time width of a pulse signal. In an AD converter for each unit pixel, a pulse generation circuit feeds back a delay signal obtained by delaying an output signal of the comparator to the comparator and arithmetically operates the output signal and the delay signal to generate a pulse signal. A latch circuit latches the pulse signal generated by the pulse generation circuit. The present disclosure can be applied to a solid-state imaging element of a stacked type and a back side illumination type.
