There is provided an ultrasound probe capable of efficiently discharging heat generated in a plurality of piezoelectric elements to the outside. A heat collecting portion that includes at least one heat conducting path and is formed of a material having a higher thermal conductivity than a backing member collects heat from a plurality of piezoelectric elements, and a heat exhausting portion connected to the heat collecting portion discharges the heat collected in the heat collecting portion to the outside. The heat conducting path extends in a thickness direction within the backing member and has a distal end exposed from the top surface of the backing member facing the bottom surface of each of the plurality of piezoelectric elements.
