The force moment sensor is a monolithic disk-shaped mounting part (20) including a flat surface. The mounting part includes a first middle portion (21) of high rigidity with first force application locations (25), at least three second portions (221 to 223) of medium rigidity configured circumferentially, each including two second force application locations (26) in the transition portion between juxtaposed second portions, strain relief portions (23) of low rigidity and at least three radially oriented connecting webs (24) and comprising a medium rigidity by a recess (27) of U-shaped cross-section being configured in the medium portions thereof. Mounted on the flat surface of the second portions (22) and of the connecting webs (24) are strain gauges (28) circuited in accordance with the principle of a Wheatstone bridge. From the measured values obtained thereby three forces (Fx, Fy, Fz) and three moments (Mx, My, Mz) can be defined.
