Abstract: An ultrasound probe includes: an acoustic matching layer having a sheet-shaped member whose both ends are bonded together by adhesive to define a cylindrical shape and configured to adjust acoustic impedance of ultrasound; piezoelectric elements arranged along a circumferential direction on an inner periphery of the acoustic matching layer and configured to emit ultrasound in response to an input signal and configured to convert ultrasound from outside into an echo signal; a disc-shaped structural member provided on one end side of the acoustic matching layer in a longitudinal direction orthogonal to the circumferential direction, a part of an outer side surface of the structural member being fixed inside the acoustic matching layer. The structural member has a water repellent portion on a part of the outer side surface such that the water repellent portion faces, in a radial direction, a gap between the both ends of the acoustic matching layer.
