Abstract
Provided is a solid-state image pickup device capable of suppressing deterioration of characteristic caused due to an antireflection film itself absorbing a light. In the solid-state image pickup device of the present invention, a plurality of color filters 8a, 8b, and 8c having spectral characteristics, respectively, different from each other are provided so as to correspond to a plurality of light reception sections 2, respectively, aligned on a semiconductor substrate 1. Further, a plurality of microlenses 10 are provided above the plurality of color filters 8a, 8b, and 8c, respectively. A plurality of antireflection films 11a are selectively formed on surfaces of the microlenses 10 provided above color filters 8b each having a predetermined spectral characteristic.
