Abstract
A solid-state image pickup element including: a photoelectric conversion region; a transistor; an isolation region of a first conductivity type configured to isolate the photoelectric conversion region and the transistor from each other; a well region of the first conductivity type having the photoelectric conversion region, the transistor, and the isolation region of the first conductivity type formed therein; a contact portion configured to supply an electric potential used to fix the well region to a given electric potential; and an impurity region of the first conductivity type formed so as to extend in a depth direction from a surface of the isolation region of the first conductivity type in the isolation region of the first conductivity type between the contact portion and the photoelectric conversion region, and having a sufficiently higher impurity concentration than that of the isolation region of the first conductivity type.
