Abstract

A sensor part for an infrared sensor, including an IR-sensitive detector (1), at least one reference source (2) emitting IR radiation, and an IR-sensitive reference detector (3) which, in the direction of the incident IR radiation, is at a distance from the detector (1), wherein the at least one reference source (2) is arranged at the side of the reference detector (3), and including a support (5), on the first side (6) of which the detector (1), the at least one reference source (2) and the reference detector (3) are arranged. The support (5) includes a blank made of a flexible material bent in some sections, in particular a blank made of a flexible printed circuit board bent in some sections. The invention achieves the aim of specifying a three-dimensional sensor part for an IR sensor that can be produced by a simple method. The invention further relates to a method for producing a sensor part and to an IR sensor.
