PROBLEM TO BE SOLVED: To provide an ultrasonic intensity distribution measuring method, for measuring an ultrasonic intensity distribution within a measured space, capable of measuring an effective ultrasonic intensity distribution from transmitting an ultrasonic wave to receiving the ultrasonic wave reflected at points within a measured space in a system of obtaining a received signal by transmitting the an ultrasonic wave within the measured space and receiving a reflected ultrasonic wave. SOLUTION: In the ultrasonic intensity distribution measuring method, a first sound pressure within the measured space is obtained by transmitting an ultrasonic wave into a measured space from a first vibrator used for transmitting the ultrasonic wave and receiving the ultrasonic wave by an ultrasonic sensor disposed within the measured space, a second sound pressure is obtained by transmitting an ultrasonic wave into the measured space from a second vibrator used essentially for receiving the ultrasonic wave and receiving the ultrasonic wave by an ultrasonic sensor disposed within the measured space, and the effective ultrasonic intensity distribution within the measured space is obtained using the first and the second sound pressures.
