A force sensing apparatus comprising: a plate-like strain producing body; a central portion disposed integrally at a center of the body and having higher rigidity than the body; a peripheral portion disposed integrally along a periphery of the body and having higher rigidity than the body; and a plurality of sensing elements formed on a surface of the body and having an electric resistance variable in accordance with a deformation thereof in order to simultaneously sense mutually orthogonal X, Y and Z axial components of an external force applied to the body via the central portion or the peripheral portion, the sensing elements being on the same plane.
