Claim 9:
10. A method of manufacturing a light detecting device, comprising:
forming a plurality of photoelectric conversion devices in an imaging device region of a semiconductor substrate in a two-dimensional array; and
forming a stacked body by stacking a plurality of layers on the semiconductor substrate, wherein
the forming of the stacked body includes:
forming an in-layer lens layer that comprises a plurality of in-layer lenses and a plurality of structures, wherein
each in-layer lens of the plurality of in-layer lenses is at a first position corresponding to each photoelectric conversion device of the plurality of photoelectric conversion devices,
the plurality of structures is at a height equal to a height of the plurality of in-layer lenses, and
the plurality of structures is on an outside of the imaging device region;

forming a planarization layer having a planarized surface, on the in-layer lens layer; and
forming an on-chip lens layer that is an upper layer than the planarization layer and that comprises a plurality of on-chip lenses,

each on-chip lens of the plurality of on-chip lenses is at a second position corresponding to each photoelectric conversion device of the plurality of photoelectric conversion devices, and
in a plan view, a first region in which the plurality of on-chip lenses is provided is smaller than a second region in which the plurality of in-layer lenses and the plurality of structures are provided.
