An intracavitary ultrasound probe includes a housing having an inset section and a holding section and an ultrasound unit built into the insertion section. A center axis of the insertion section is offset with respect to a center of a cross section perpendicular to a longitudinal direction of the holding section. The holding section has a first outer surface portion and a second outer surface portion and a curvature of the first outer surface portion is smaller than a curvature of the second outer surface portion on the cross section perpendicular to the longitudinal direction.
