Abstract
According to an aspect, a force detection apparatus includes: a first electrode facing an input surface to which an object to be detected applies a force; a second electrode facing the first electrode across a first layer deformable by the force; a conductor facing the second electrode across a second layer deformable by the force; and a force detection controller calculates a force signal value indicating the force, based on a first influence amount and a second influence amount, the first influence amount being an amount of influence added by the force to first capacitance between the first electrode and the second electrode, and the second influence amount being an amount of influence added by the force to second capacitance between the second electrode and the conductor.
