The present invention relates to an ultrasound therapy system using high-intensity focused ultrasound. The ultrasound therapy improves ultrasound and heat release characteristics and provides an ultrasound probe which easily performs manufacturing and maintenance processes. According to the present invention, a housing is recessed on the inward side around the upper-part edge. A plurality of mounting holes is uniformly formed from the outside at a constant radius to the edge in the center of the upper part. A plurality of probe units is respectively installed in the plurality of mounting holes to form a sphere on the upper part of the housing. And a grounding film covers the sphere which the plurality of probe units forms. At this point, the probe unit has a structure that a first connection pin is protruded to the lower part of the housing in the lower part of a copper connection bar and a rear block, a piezoelectric wafer, and an acoustic matching layer are sequentially stacked on the upper part of the connection bar. The upper surface of the probe units installed on the housing, the acoustic matching layer, forms the sphere. The grounding film is formed on the acoustic matching layer. A cover layer can be formed on the grounding film.
