A force sensor, in particular for the determination of the forces on a vehicle seat, includes a force measuring cell (1; 19) having a Hall element. The force measuring cell (1; 19) contains a hollow-cylindrical flexible element (2; 23), which, based on the force effect (F) to be determined, causes an affect of the magnetic field in the region of the magnetic field-sensitive sensor element (11) of the force measuring cell (1; 19). The hollow-cylindrical flexible element (2; 23) contains a bar (4) on a relatively stationary end on a first support part with a magnet (5) on its free end. The flexible element held on one support part (26) projects into a top (20) held on the other support part (7), whereby the top (20) has a radially extending inner collar (21) in the region of mounting on the other support part (7). The inner collar overlaps radially a widening of diameter (22) of the flexible element (23) located in the interior of the top (20).
