Solid-state imaging device, imaging apparatus, and method of manufacturing solid-state imaging device

There is provided a solid-state imaging device including a semiconductor substrate on which photoelectric conversion devices are arranged in an imaging device region in a two-dimensional array, and a stacked body formed by stacking layers on the semiconductor substrate, wherein the stacked body includes an in-layer lens layer that has in-layer lenses each provided at a position corresponding to each of the photoelectric conversion devices, a planarization layer that is stacked on the in-layer lens layer and that has a generally planarized surface, and an on-chip lens layer that is an upper layer than the planarization layer and that has on-chip lenses each provided at a position corresponding to each of the photoelectric conversion devices, and the in-layer lens layer has structures at a height generally equal to a height of the in-layer lenses, the structures being provided on an outside of the imaging device region.
