PROBLEM TO BE SOLVED: To provide an ultrasonic endoscope in which the outer diameter of an insertion part can be formed to be narrow, entanglement of incorporated objects with one another is reduced and electric safety of a connection part is surely and simply secured even in a structure that a balloon liquid supply path through which a liquid sent into a balloon passes and a balloon liquid discharge path through which the liquid discharged from the balloon passes are inserted and arranged inside the insertion part over the entire length. SOLUTION: In the ultrasonic endoscope, the balloon liquid supply path 6i and the balloon liquid discharge path 6o are formed of a flexible multi-lumen tube 6 where two independent flow paths are arranged side by side in one tube over the entire length.
