Provided is an ultrasound probe with which it is possible to avoid resolution degradation in an ultrasound image, and furthermore, to highly reliably withdraw an ultrasound oscillator electrode. The ultrasound probe comprises an ultrasound oscillator, an electrode withdrawal layer, and a low audio impedance adjustment layer. The ultrasound oscillator further comprises a plurality of elements which are arrayed at a prescribed pitch. The electrode withdrawal layer is electrically connected to the ultrasound oscillator. The low audio impedance adjustment layer is disposed upon the electrode withdrawal layer, has a lower audio impedance than the ultrasound oscillator, and is in a sheet shape wherein a plurality of grooves are formed in the face on the electrode withdrawal layer side in parallel in the direction of the element array.
