1. A light detection device, comprising:
a semiconductor substrate having a light receiving region where a plurality of cells are arranged in a first direction;
a plurality of pad electrodes which are arranged on the semiconductor substrate and each of which is electrically connected to the cell corresponding thereto among the plurality of cells; and
a plurality of wires each of which is connected to the pad electrode corresponding thereto among the plurality of pad electrodes,
wherein a stitch bond of a corresponding wire among the plurality of wires is formed on each of the pad electrodes,
a distance between each of the pad electrodes and the cell corresponding to the pad electrode is smaller than a distance between the pad electrodes connected to mutually different cells of the cells,
the plurality of pad electrodes are arranged in a first region and a second region that are spaced apart from each other with the light receiving region interposed therebetween in a second direction crossing the first direction,
the plurality of cells include a plurality of cell groups including a first cell and a second cell adjacent to each other,
the pad electrode corresponding to the first cell is arranged in the first region, and
