Abstract: A capacitance detection device for detecting a capacitance between a detection electrode and an object in proximity to the detection electrode includes the detection electrode configured to detect a capacitance between the detection electrode and the object, an active shield electrode disposed in proximity to the detection electrode, a voltage output circuit for outputting an alternating voltage to be supplied to the active shield electrode, a first adjustment circuit for adjusting an amplitude of an alternating voltage output from the voltage output circuit, and a first operational amplifier for amplifying and outputting a voltage difference between an inverting input terminal thereof connected to one end of the detection electrode and a non-inverting input terminal thereof to which an alternating voltage adjusted by the first adjustment circuit is applied. The detection electrode has, between one end and the other end thereof, a resistance value from 5 kΩ to 270 kΩ.

Abstract: A capacitance detection device includes at least one detection electrode, a shield electrode disposed in close vicinity of the detection electrode, an AC signal source that supplies an AC signal to the shield electrode, a detection circuit that detects capacitance between a physical object in close vicinity of the detection electrode and the detection electrode on the basis of a detection signal output from the detection electrode and the AC signal output from the AC signal source, and a phase adjustment circuit provided between the AC signal source and the shield electrode. The phase adjustment circuit advances the phase of the AC signal output from the AC signal source.
