A force sensor with two force input elements to which a force to be measured and a support force are applied. The two force input elements are substantially rotationally symmetrical and are axially spaced apart, and the force to be measured and the support force are applied in radial directions. A spring element, arranged axially between the two force input elements connects these elements and its load-dependent deformation is converted into an electrical signal. A suppression of transverse forces is achieved in a purely mechanical manner so that the influence of transverse forces on the output signal of the force sensor are negligible. Both force input elements are additionally connected to each other by a guide element which encloses the spring element and which has two parallel guide connectors. The guide element is softer in the direction of the force to be measured than in a direction perpendicular thereto.
