Beschreibung
Zusammenfassung:	An infrared detecting device includes a substrate and a thermal photo detecting element. The substrate includes a concave portion, and a frame portion positioned on the periphery of the concave portion. The thermal photo detecting element includes leg portions and a detecting portion. The leg portions are connected on the frame portion so that the detecting portion is positioned above the concave portion. The thermal photo detecting element includes a first electrode layer disposed on the substrate, a detecting layer disposed on the first electrode layer, and a second electrode layer disposed on the detecting layer. The linear thermal expansion coefficient of the first electrode layer is larger than the linear thermal expansion coefficient of the substrate. The linear thermal expansion coefficient of the substrate is larger than the linear thermal expansion coefficient of the detecting layer.
