The ultrasound probe according to this embodiment comprises a piezoelectric transducer, a backing material, and a flexible substrate. The piezoelectric transducer has electrodes on each of a front face facing the radiation direction of ultrasound waves and a back face facing the opposite direction. The backing material is provided on the back face side of the piezoelectric transducer, and has a first width substantially equal to the width of the piezoelectric transducer widthwise and perpendicular to the radiation direction of the ultrasound waves. The flexible substrate is located between the backing material and the piezoelectric transducer, with a wiring pattern provided on the face on the piezoelectric transducer side. In addition, the flexible substrate is folded in a direction substantially opposite the radiation direction around an end of the backing material widthwise. Moreover, the wiring pattern of the flexible substrate is covered by a covering member. In addition, the front face of the layer located on the front face side with regard to the wiring pattern has a width substantially equal to said first width and the back face of this layer is formed to have a second width shorter than said first width. Furthermore, a space is provided between this layer and the backing material due to the difference between the first width and the second width of this layer. Additionally, the covering member covers the wiring pattern extending at least from the folded section of the flexible substrate into the space.
