Abstract
A force detection apparatus includes: a force detector that includes an electrode and a conductor facing the electrode across a first and a second layers and outputs a force signal value before correction; and a force detection controller outputting a force signal value after correction having a linear relationship with a force. In a first range of force in which the first layer is deformed and the second layer is not deformed, the force detection controller calculates the force signal value after correction, based on a product of the force and a first constant. In a second range of force in which the first and second layers are deformed, the force detection controller calculates the force signal value after correction, based on a sum of a product of a threshold and the first constant and a product of a difference between the force and the threshold and a second constant.
