An ultrasonic device includes a substrate, a transmitter provided at the substrate and configured to transmit an ultrasonic wave to an object, and a receiver provided at a position different from the transmitter at the substrate and configured to receive an ultrasonic wave reflected by the object. A resonance frequency of the transmitter is higher than a resonance frequency of the receiver. An anti-resonance frequency of the receiver is included in a predetermined frequency band including the resonance frequency of the transmitter.
