PROBLEM TO BE SOLVED: To provide a therapeutic device for relieving constipation (regularity or evacuation) by stimulating pressure points or nerves related to constipation from the outside of the human body.SOLUTION: An ultrasonic constipation relieving device includes: an ultrasonic signal oscillation circuit a head put between a third lumbar vertebra and a fourth lumbar vertebra, between the fourth lumbar vertebra and a fifth lumbar vertebra, or one or more place near the third lumbar vertebra to the fifth lumbar vertebra from the outside of the back and a piezoelectric vibrator for generating ultrasonic waves vibrated by an ultrasound signal oscillated by the ultrasonic signal oscillation circuit and transmitted to the lumbar vertebra or inter-lumbar vertebras from the outside of the back. The piezoelectric vibrator is fixed to the head made of a hard material to which ultrasonic vibration generated therefrom is easily transmitted. The piezoelectric vibrator generates ultrasonic vibration ranging from 1.5 to 2.0 MHz. The head is large enough to be put between the third lumbar vertebra and the fourth lumbar vertebra, between the fourth lumbar vertebra and the fifth lumbar vertebra, or to one or more of the third lumbar vertebra to the fifth lumbar vertebra, has enough output strength to stimulate the pressure points and nerves related to the constipation, and outputs ultrasonic vibration of the frequency.
