1. A detection device, comprising:
a sensor including a driving electrode and detection electrodes; and
a controller detecting a non-contact target from signal waveforms acquired from the detection electrodes by applying a voltage to the driving electrode, the signal waveforms each indicating a change in signal strength over time,
wherein the controller discriminates a peak caused by the non-contact target on the basis of a time width from a rising start point of a peak to a peak top of the peak, a height from the rising start point of the peak to the peak top of the peak, and a slope of a rising side of the peak, in the signal waveform.
