Fluid sensor containing a fluid cell (1) to enclose a volume of fluid (7), i.e. a gas or liquid, that is to be analysed and a method for producing such a fluid sensor. The fluid sensor comprises an electromagnetic energy source (3 ) arranged to transmit electromagnetic waves (4) into the fluid cell (1) and a t least one detector (5) to detect electromagnetic waves passing through the fluid cell (1) and at least one opening (2) for the inlet/outlet of a fluid that is to be analysed. The fluid sensor also comprises a circuit board (8, 10, 11, 12, 13, 14, 15, 16) to evaluate the intensity of electromagnetic wav es reaching said at least one detector (5) and/or to provide the circuitry for the electromagnetic energy source (3). At least part of the fluid cell (1) i s incorporated into the substrate of the circuit board (8, 10, 11, 12, 13, 14, 15, 16).
