1. A light detecting element comprising:
a light detecting surface comprising:
a plurality of light detecting regions disposed in a row in a first direction, the plurality of light detecting regions including:
a first light detecting region, which is an outermost one of the light detecting regions at a first end of the row, and
a second light detecting region, which is an outermost one of the light detecting regions at a second end of the row opposite the first end, wherein:
each of the plurality of light detecting regions is longer in a second direction than in the first direction, the second direction being perpendicular to the first direction, such that each light detecting region has a pair of lateral edges that extend in the first direction and pair of longitudinal edges that are longer than the lateral edges and extend in the second direction, and
a plurality of wiring regions electrically connected to the plurality of light detecting regions, the plurality of wiring regions including:
a first wiring region electrically connected to the first light detecting region, and
a second wiring region electrically connected to the second light detecting region, wherein:
in a top view, the first and second wiring regions are located in an end region of the light detecting surface located outward of a central region of the light detecting surface, and are not located in the central region, the central region being defined as a region between (i) a straight line extending in the second direction on an outermost longitudinal edge of the first light detecting region and (ii) a straight line extending in the second direction on an outermost longitudinal edge of the second light detecting region, and
in a top view, the plurality of wiring regions are located between straight lines extending in the first direction on outermost opposite lateral edges of the light detecting regions.
