Abstract: Disclosed is a force sensor and an apparatus having the sensor for measuring weight. The force sensor and apparatus can enhance detection sensitivity by amplifying a displacement of an elastic body having high strength, thereby measuring weight. The sensor includes: a base; an elastic structure provided as a housing disposed on the base, and downwardly deformed when weight is applied to the elastic structure; an adjusting member coupled to an upper surface of the elastic structure by penetrating the upper surface; a lever disposed below the elastic structure, and amplifying a displacement of the elastic structure transferred via the adjusting member by being in contact with the adjusting member; a sensor disposed above the base, and generating an electric signal indicative of a distance from the sensor to the lever; and a circuit board disposed between an upper surface of the base and a lower surface of the sensor.
