Abstract
An ultrasonic sensor is a sensor that transmits an ultrasonic wave to a target object and receives the ultrasonic wave reflected by the target object, the ultrasonic sensor including an ultrasonic array chip on which ultrasonic elements that transmit and receive the ultrasonic wave are arranged in an array shape. Each of the ultrasonic elements includes a vibrating section and a piezoelectric element provided in the vibrating section, vibrates the vibrating section to transmit the ultrasonic wave, and outputs a reception signal of the ultrasonic wave by the vibration of the vibrating section. A resonance frequency of the ultrasonic element is 2000 kHz or less.
