PROBLEM TO BE SOLVED: To provide a highly rigid and sensitive force sensor capable of preventing a drift from being generated even when measuring a static load. SOLUTION: This force sensor has an upper plate 2b of a force applying part for receiving the load as a measuring object to be deformed elastically, a displacement magnifying mechanism 3 for magnifying a displacement amount of the upper plate 2b, and a strain gage displacement sensor 4 for measuring the displacement amount of the upper plate 2b magnified by the displacement magnifying mechanism 3. The displacement magnifying mechanism 3 may comprise a plurality of levers 35, 36, and the displacement sensor 4 may measure the displacement amount where the one application point is overlapped with the power point of the adjacent lever, out of power points, fulcrums and application points of the levers 35, 36, to magnify the displacement amount of the upper plate 2b with a magnification multiplied by magnifications of the levers 35, 36.
