ABSTRACT:
A solid-state imaging device provided with a light receiving surface, in which plural unit pixels, each having a photoelectric transducer to convert light signals into electric signals, are two-dimensionally arranged; a microlens to focus a light beam, the microlens being arranged in each unit pixel corresponding to the photoelectric transducer; an aperture section, to allow the light beam to enter the photoelectric transducer, the aperture section being arranged in each unit pixel corresponding to the photoelectric transducer; a wiring layer, which comprises plural layers, and is formed between the photoelectric transducer and the microlens, wherein the plural unit pixels are arranged such that each of the photoelectric transducer is located axisymmetrically with a symmetrical axis of a first centerline passing through an approximate center of the light receiving surface.
