1. A solid-state imaging device, comprising:
a plurality of pixel units including on-chip lenses, color filters, and photoelectric conversion units; and
a lattice-shaped inter-color-filter light-shielding portion formed on a side of light incident surfaces of the photoelectric conversion units so as to surround the respective color filters of the plurality of pixel units,
the plurality of pixel units including a first pixel unit and a second pixel unit, the first pixel unit including an on-chip lens of a predetermined size, the second pixel unit including an on-chip lens of a size larger than the predetermined size, the first pixel unit including first pixel units, the second pixel unit including second pixel units,
a height of the inter-color-filter light-shielding portion surrounding the respective color filters of the second pixel units being larger than a height of the inter-color-filter light-shielding portion between the respective color filters of the first pixel units.
