Abstract
An infrared sensor substrate includes: column signal lines; row signal lines; a pixel array of pixels including infrared detector elements connected to the column signal lines and the row signal lines. The infrared sensor substrate includes: a current source connected to the infrared detector elements via the column signal lines; a voltage source that applies a voltage to the infrared detector elements via the row signal lines; output terminals connected to the column signal lines, the output terminals being connectable to a signal processing circuit substrate that processes output signals of the infrared detector elements. The infrared sensor substrate includes a monitoring terminal capable of monitoring the voltage applied to the infrared detector elements by the first voltage source.
