1. A light detecting device, comprising:
a pixel region that is formed on a light incident side of a first substrate and in which a plurality of pixels that include photoelectric conversion units is arranged;
a circuit unit that is formed in a second substrate below at least one of the plurality of pixels in the first substrate;
a first multilayer-wiring layer that includes a first wiring layer having a first wiring and a second wiring layer having a second wiring; and
a second multilayer-wiring layer formed at a side of the second substrate, wherein the second multilayer-wiring layer includes a third wiring layer having a third wiring and a fourth wiring layer having a fourth wiring, and wherein the first substrate and the second substrate are stacked;
wherein,
the first multilayer-wiring layer and the second multilayer-wiring layer are disposed between the pixel region and the circuit unit, and
one of the first wiring, the second wiring, the third wiring or the fourth wiring, extending in a first direction, at least partially overlaps with another of the first wiring, the second wiring, the third wiring or the fourth wiring extending in the first direction.
