3. The solid-state image device according to claim 2 , wherein each of the first height difference portions is arranged the first interval away from the nearest other first height difference portions.
4. The solid-state image device according to claim 3 , further comprising:
a second height difference portion formed on the first substrate,
wherein the second height difference portion is placed a second interval away from the first height difference portions in a direction perpendicular to the direction in which the first height difference portions are arranged, the second interval being shorter than the first interval.
5. A solid-state image device comprising:
a color filter formed on a first substrate; and
a plurality of first height difference portions formed into a quadrangular prism on the first substrate,
