Abstract
In a light detection device, each pixel includes a plurality of APDs. Each APD forms a light receiving region and is configured to operate in a Geiger mode. The plurality of APDs forms a plurality of light receiving regions arranged in a direction along a main surface in a pixel area α occupied by a corresponding pixel among a plurality of pixels. The MOS switch circuit region overlaps with the plurality of light receiving regions when viewed from a Z-axis direction. When viewed from the Z-axis direction, the area of the MOS switch circuit region is greater than the area of one light receiving region formed in the pixel area, and less than or equal to the area of the pixel area. A plurality of APDs included in each pixel is electrically connected in parallel to each other and each is connected to a MOS switch circuit.
