In a case where the amplitude of a detection voltage is increased, the amplitude of a drive current flowing in a detection-target capacitor also increases, and thus, the amplitude of a detection current also increases. In this case, the increase in amplitude of the detection current is not directly restricted by the condition of a power supply voltage range enabling a circuit to operate. For this reason, a current conversion ratio of a current output circuit or a capacitance value of a capacitor of a current-voltage conversion circuit is set to an appropriate value so as not to cause a voltage to exceed the power supply voltage range, thereby preventing the amplitude of the detection current from being restricted by the condition of the power supply voltage range. Therefore, it is possible to increase the amplitude of the detection voltage to a maximum within the power supply voltage range.
