Abstract
A detection device includes an electrostatic capacitance sensor including an electrode pair and being configured to detect electrostatic capacitance of a medium brought into contact with the electrode pair, and a first ultrasonic wave sensor including a first transmission unit configured to transmit an ultrasonic wave and a first reception unit configured to receive an ultrasonic wave transmitted from the first transmission unit. The transmission unit and the reception unit are positioned to sandwich the medium.
