PROBLEM TO BE SOLVED: To provide a sensor capable of improving the sensitivity of an infrared sensor.SOLUTION: The sensor includes: a ferroelectric substance element 10 having a first electrode 11, a second electrode 12 and a ferroelectric film 13 disposed between the first electrode and the second electrode, and composed of a ferroelectric substance; and detection means 20 for reading a charge generated in the ferroelectric substance element. The detection means is configured to apply a first voltage for aligning the polarization directions of the ferroelectric film and a second voltage for inverting the polarization of at least a part of the ferroelectric film whose polarization directions are aligned, and to perform reading. |
