Detection device

A detection device comprising:

• a substrate;
• a plurality of photoelectric conversion elements provided to the substrate and each comprising a semiconductor layer having a photovoltaic effect;
• a plurality of transistors provided for each of the photoelectric conversion elements;
• and
• a plurality of signal lines, each of which is provided between the photoelectric conversion elements adjacent to each other in a first direction, extends in a second direction intersecting the first direction, and is configured to supply a signal to any one of the photoelectric conversion elements and the transistors, wherein
• each of detection elements comprises one of the photoelectric conversion element and the transistors arranged adjacent to the photoelectric conversion element in the second direction,
• a first signal line among the signal lines is arranged between the photoelectric conversion element of a first detection element and the photoelectric conversion element of a second detection element adjacent to one side in the first direction of the first detection element, and is coupled to the first detection element and the second detection element, and
• a second signal line among the signal lines is arranged between the photoelectric conversion element of the first detection element and the photoelectric conversion element of a third detection element adjacent to another side in the first direction of the first detection element, and is coupled to the first detection element and the third detection element.
