Patent attributes
A detector includes a semiconductor layer included in a detection region and a peripheral region, and having a first surface and a second surface opposite to the first surface, and a wiring structure included in at least the detection region, and disposed between a space on the first surface side with respect to the semiconductor layer and a space on the second surface side with respect to the semiconductor layer, wherein a thickness of the semiconductor layer in at least a part of the detection region is smaller than a thickness of the peripheral region including the semiconductor layer, and the thickness of the semiconductor layer is larger than a distance between the first surface in the detection region and the space on the first surface side, and a distance between the second surface in the detection region and the space on the second surface side.
