Abstract: There is provided an infrared array sensor, which is capable of positional specification and flow tracking of an object to be detected without performing image processing, and whose cost is low. An infrared array sensor 100 where pixels 101, each having a thermal infrared detector 102 whose electric properties change in accordance with incidence of infrared rays, are arrayed in two-dimensional matrix form, the infrared array sensor 100 including: a row output take-out means 103 configured so as to take out an electric signal to the outside as an output, the electric signal being in accordance with electric properties as a sum of electric properties respectively shown by the thermal infrared detectors 102 on each row; and a column output take-out means 104 configured so as to take out an electric signal to the outside as an output, the electric signal being in accordance with electric properties as a sum of electric properties respectively shown by the thermal infrared detectors 102 on each column.
