Abstract
In a rigid distal end portion of an ultrasonic endoscope, a side-viewing optical observation portion and a wave transmission/reception face of an ultrasonic probe are provided on respective sides, in the width direction, of a boundary side wall of a pair of side walls constituting a laterally open recess. The wave transmission/reception face is arranged in a range in which at least a part of the wave transmission/reception face overlaps the boundary side wall, while being offset from an elevator in the longitudinal direction of an insertion portion. When the rigid distal end portion is viewed in an observation direction of the optical observation portion, a top portion of the elevator is located on a line connecting a center of the outer shape of the wave transmission/reception face of the ultrasonic probe, and a center, in the width direction, of the distal end connecting portion of a treatment tool conduit.
