To measure respiration at the place away from a person to be measured without affecting any mental influence by measuring the change of temperature at the section such as nostrils or the chin on the face with the passage of time and measuring the respiration.
A thermal imaging device 10 is composed of an infrared thermal image sensor 11, a filter 12 integrally fitted to the infrared thermal image sensor 11, a monitor 13 connected to the infrared thermal image sensor 11, and a personal computer main body 14. When measuring the respiration, heat radiation discharged from the forehead or exhalation of a person M to be measured is fetched through the filter 12 by the infrared thermal image sensor 11 as data and processed by the personal computer main body 14, and the change of temperature with the passage of time is displayed on the monitor 13. Thus, since the condition of respiration can be recognized in non-contact state away from the person to be measured, the respiration can be exactly measured without applying any mental influence or sense of incompatibility to the person to be measured.
