PROBLEM TO BE SOLVED: To verify the moving state of an object to be measured in real time by simultaneously measuring three-dimensional coordinate positions of a plurality of locations at which the object to be measured rests still or moves through the use of a direct wave system of individual ultrasonic waves having different frequencies, transmission start times, or transmission intervals. SOLUTION: This three-dimensional coordinate measuring apparatus using ultrasonic waves is provided with an ultrasonic transmitter 10 mounted to a prescribed part of the body of a subject to be measured 900 for transmitting the ultrasonic waves having different frequencies; a trigger device 20 for synchronizing the ultrasonic waves 150 having different frequencies and transmitted from the ultrasonic transmitter 10; a receiver 30 for receiving the ultrasonic waves 150 having different frequencies and transmitted from the ultrasonic transmitter 10; an analyzer 40 for detecting a three-dimensional coordinate position at high speeds at which the subject to be measured 900 is located by analyzing the ultrasonic waves 150 received by the receiver 30; a display means 50 for displaying the location of the body of the subject to be measured 900 on the basis of the results of analysis of the analyzer 40; a data storage device 60; a contrast device 70; and a notification device 80.
