Abstract
A solid-state imaging element includes a semiconductor substrate that has a light reception portion performing a photoelectric conversion of an incident light; an oxide layer that is formed on a surface of the semiconductor substrate; a light shielding layer that is formed on an upper layer further than the oxide layer via an adhesion layer; and an oxygen supply layer that is disposed between the oxide layer and the adhesion layer and is formed of a material which shows an oxidation enthalpy smaller than that of a material forming the oxide layer.
