An ultrasonic wave output device includes a plurality of ultrasonic wave output units and an overlapping range change unit. The plurality of ultrasonic wave output units are arranged along a horizontal direction in a vehicle. Each of the plurality of ultrasonic wave output units emits an audible sound generated with ultrasonic waves, which have a same phase, to corresponding one of a plurality of sound areas. The plurality of sound areas indicate predetermined areas. The overlapping range change unit changes a range of an overlapping area, which indicates an area on which the plurality of sound areas overlap, in response to an external instruction.
