    (54) ABNORMALITY DIAGNOSTIC DEVICE


    (57) An abnormality diagnosis apparatus includes a sensor unit 2 configured to detect a heat flux which flows from a target apparatus 200 toward outside, and a determining unit 3 configured to determine an abnormality of the target apparatus 200. The sensor unit 2 includes a first heat flux sensor, a second heat flux sensor, and a thermal buffer which is disposed between the first heat flux sensor and the second heat flux sensor and which has predetermined heat capacity. The first heat flux sensor outputs a first sensor signal in accordance with a heat flux which passes through the first heat flux sensor from the target apparatus 200 side toward the thermal buffer side. The second heat flux sensor outputs a second sensor signal in accordance with a heat flux which passes through the second heat flux sensor from the thermal buffer side toward a side farther from the target apparatus 200. The determining unit 3 determines whether or not there is an abnormality of the target apparatus 200 on the basis of the first sensor signal and the second sensor signal.
