An ultrasound probe to be connected to an ultrasound diagnostic apparatus body, including an acoustic element that mutually converts an electrical signal and an ultrasonic signal, a motor that causes the acoustic element to perform rocking rotation, a frame that is formed from a resin with thermal conductive properties and that holds the acoustic element so as to allow rocking thereof, and an acoustic window that is formed from an ultrasound-transmitting material and that forms, together with the frame, a closed space that contains the acoustic element and a coupling liquid such that the motor is disposed outside the closed space.
