The present invention relates to an ultrasound therapy and a cosmetic device. In general, the configuration of the ultrasonic beauty machine is divided into a probe head, a main body, and an ultrasonic oscillation control unit. In the ultrasonic beauty device, the probe is in direct contact with the skin to transmit ultrasound. The material of the probe is made of metal, for example, titanium or stainless steel. For this reason, the material should not be corrosive and chemically stable for people with sensitive skin and free of harmful elements. However, in the present invention, the material of the probe is not a metal, but is usually used as a bracelet and a necklace, such as natural jewelry, such as agate or a natural jade plate (1) for contacting the skin using a material such as agate That's the way it is. At this time, the part to be thought of should be good vibration transmission of the ultrasonic wave, the hardness and breakage should be implemented in a manner that is not easy, and the purpose of modularization of the head shape that is easy to replace when unexpected breakage. At the same time, jade heads, such as semi-jewelries, are expected to become a material that is skin-friendly from the user's touch and looks like a jewelry. The present invention is an invention designed to be used as a probe of an ultrasonic beauty device and a medical device that compensates for the above problems, and is considered as the best ultrasonic beauty device probe. To realize this, a disc-shaped skin contact jade plate (1) contacting the human skin with thin agate or jade stone (1) and a metal plate (2) attached with a disc-shaped jade plate (2): (copper, stainless steel or aluminum The ceramic ultrasonic vibrating element 3 is attached to the rear surface thereof. In addition, it is configured in a detachable manner in order to damage and change the use and is connected to the main body by a lead wire 4 connecting the oscillation circle. The socket type module, which
