The present invention relates to a fungal treatment or nail care system using ultrasound, more specifically at least one ultrasound probe for irradiating ultrasound to the lesion site of the user； And a main body configured to control the ultrasonic wave oscillated by the ultrasonic probe, wherein the ultrasonic probe comprises: an upper probe constituting an upper portion of the ultrasonic probe and including an ultrasonic wave oscillator for oscillating the ultrasonic wave according to the adjustment of the main body； A lower probe supporting a user's finger or toe and having one end connected to the upper probe and the other end spaced apart from the upper part such that the user's finger or toe can be inserted； A connection part connecting the one end of the upper probe and the lower probe to bend so that the other ends of the upper probe and the lower probe are spaced apart from each other so as to control the separation distance； And a gel pad provided under the ultrasonic oscillation unit to increase contact between the ultrasonic oscillation unit and the lesion site of the user. According to the present invention, a fungal treatment or nail care system using ultrasonic waves, by providing a gel pad in the lower portion of the upper probe of the ultrasonic probe including the ultrasonic wave oscillator, the contact of the lesion site of the user to increase the ultrasonic Increasing the application efficiency and increasing the absorption rate of the early fungal therapeutic drug applied to the lesion site of the user can improve the therapeutic effect. In addition, according to the present invention, since a plurality of ultrasonic probes can be provided, a plurality of nails can be treated at the same time, and by using a disposable gel pad, secondary infection of early fungi by other users can be prevented.본 발명은 초음파를 이용한 조갑 진균 치료 또는 네일 케어 시스템에 관한 것으로서, 보다 구체적으로는 사용자의 병변 부위에 초음파를 조사하는 적어도 하나 이상의 초음파 프로브； 및 상기 초음파 프로브로 발진되는 초음파를 조절하는 본체를 포함하며, 상기 초음파 프로브는, 상
