Abstract:
A solid-state image pickup element 1 is structured so as to include: a semiconductor layer 2 having a photodiode formed therein, photoelectric conversion being carried out in the photodiode; a first film 21 having negative fixed charges and formed on the semiconductor layer 2 in a region in which at least the photodiode is formed; and a second film 22 having the negative fixed charges, made of a material different from that of the first film 21 having the negative fixed charges, and formed on the first film 21 having the negative fixed charges.
