The sensor device (10) has a housing (12) and a deformation body (20) received in the housing. A pressure plate (30) is coupled to the deformation body, in which a local external force (F) is introduced, such that the deformation body is locally deformed. The deformation body has a support portion (24) fixed relative to the housing, and a force introduction portion (26), on which the external force to be introduced into the pressure plate acts. A bending portion (23) connecting the support portion to the force introduction portion is deformable with the introduction of the external force.
