Abstract
An ultrasonic sensor includes an ultrasonic transceiver that transmits and receives an ultrasonic wave, and that outputs a reception signal by receiving the ultrasonic wave, and a position detection unit that detects a position of a target facing the ultrasonic transceiver, based on the reception signal. A plurality of the ultrasonic transceivers are arranged along a first direction. The position detection unit detects inclination of the target with respect to the first direction, based on the reception signals output from a plurality of the ultrasonic transceivers.
