In a solid-state image pickup device including a light receiving sensor
portion in a surface layer portion of a substrate, an in-layer lens
disposed above the light receiving sensor portion, a color filter
disposed on the in-layer lens, and an interlayer film disposed below the
in-layer lens, an antireflection film is formed between the in-layer lens
and the color filter, the antireflection film being formed of material
having a refractive index which is an intermediate value between the
refractive index of the in-layer lens and the refractive index of the
color filter. Further, another antireflection film is formed between the
in-layer lens and the interlayer film, the other antireflection film
being formed of material having a refractive index which is an
intermediate value between the refractive index of the in-layer lens and
the refractive index of the interlayer film.
