The present invention relates to a high-output ultrasound probe wherein the ultrasound probe uses a synthetic piezoelectric element comprising a piezoelectric wafer in which a piezoelectric material is constituted in the form of a lattice, and a polymer which fills the spaces in the lattice of the piezoelectric wafer. The ultrasound probe has a high output while at the same time having a wide bandwidth, and the temperature of the acoustic lens that comes into contact with the patient can be reduced by also including a heat discharge part for discharging the heat generated in the ultrasound probe to the outside.
