Abstract
It is possible to provide a smaller-sized and higher resolution solid-state imaging device by making it possible to adjust a focal position without considerably changing a radius of curvature of a microlens formed on a photosensor portion and without increasing a thickness of a layer on the photosensor portion. A microlens (17) is formed at a corresponding position on a sensor portion (2). A layer (18) having low refractive index as compared with refractive index of the microlens (17). A solid-state imaging device (10) having an uppermost surface thereof formed as a substantially flat surface is arranged.
