Abstract
A touch detection apparatus that detects a touch to a capacitive touch sensor is provided. The touch detection apparatus includes: a capacitive dummy sensor that is disposed to an operation portion; a capacitance detector that detects values of capacitances of the touch sensor and the dummy sensor; and a touch determination portion that determines whether the touch sensor is touched and that disables determination. Multiple dummy sensors are disposed corresponding to multiple touch sensors. The touch determination portion disables the determination of whether the touch sensor disposed in a vicinity of the one of the dummy sensors is touched.
