摘要：
An ultrasound endoscope has an ultrasound probe which is disposed at a distal end side of a distal end rigid portion configuring a distal end portion out of a flexible tube portion, a bending portion and the distal end rigid portion configuring an insertion portion, and forms an ultrasound scanning surface having a normal line in a direction orthogonal to an endoscope insertion axis L1, and a treatment instrument outlet of a treatment hole in the distal end rigid portion. The ultrasound probe is configured by a plurality of ultrasound transducers arranged in a convex circular arc shape, and a center of curvature of the plurality of ultrasound transducers is disposed at a proximal end side from the treatment instrument outlet.
