A fluid-filled elastic hollow body 2, includes a pressure sensor 4 for detecting the pressure of the fluid in the elastic hollow body, and an adapter 6 for coupling the elastic hollow body to an external movable member. The elastic hollow body 2, having a hollow sphere portion 2a having a roughly constant wall thickness, is deformed when an external contact load is applied causing a rise in its inner pressure detected by the pressure sensor 4. The invention provides: (1) that the sensor can accurately measure a contact load without being influenced by a change in direction of force measured; (2) that it can be attached easily and measure a load immediately after attachment; (3) that it is resistant against instantaneous shock load; (4) that it can easily model a substance when it comes in contact therewith; and (5) that its sensitivity does not deteriorate.
