The invention relates to a force sensor with two force input elements (3,5/6), to which the force for measuring and the support force (11) are supplied, whereby both force input elements are embodied to be essentially rotationally symmetrical, separated in the axial direction and the force for measuring and the support force are introduced in the radial direction. A spring element (2), arranged in the axial direction between the both force input elements, connects the same and the load-dependent deformation thereof is converted into an electrical signal, for example, by means of strain measurement strips (25). According to the invention, a suppression of transverse forces can be achieved in a purely mechanical manner to such a degree that the influence of transverse forces on the output signal of the force sensor can be ignored, whereby the both force input elements (3,5/6) are additionally connected to each other by means of a guide element (42) which encloses the spring element (2) and which comprises two connectors (44) as parallel guide, significantly softer in the direction of the force (11) to be measured than in the direction perpendicular thereto.
