Abstract
A force sensor that quantitatively detects an external force. The force sensor comprises a base unit, a displacement unit displacing by an external force, a first displacement sensor pair including two sets of sensors detecting a relative displacement between the base unit and the displacement unit in a first direction, and a second displacement sensor pair including two sets of sensors detecting a relative displacement between the base unit and the displacement unit in a second direction. Among four quadrants divided by two straight lines along each of the first direction and the second direction wherein, the straight lines passing through a midpoint of the two sets of sensors composing the first displacement sensor pair, the two sets of sensors composing the second displacement sensor pair are respectively disposed in two quadrants in which the two sets of sensors composing the first displacement sensor pair are respectively disposed.
