PROBLEM TO BE SOLVED: To provide an ultrasonic endoscope capable of cleansing a tip opening part of a balloon suction pipeline and/or a balloon injection pipeline with a flexible cleansing brush inserted into the balloon suction pipeline and/or the balloon injection pipeline. ! SOLUTION: An ultrasonic endoscope includes an ultrasonic probe 45 covered with a balloon, a tip hard part 19 for supporting the ultrasonic probe, balloon suction pipelines 31 and 54 in which a tip opening part 37 formed at one end opens in a balloon fitting part 52 on the surface of the tip hard part, and balloon injection pipelines 35 and 53 in which a tip opening part 33 formed at one end opens at a position different from the tip opening part of the balloon fitting part. A part provided to the tip hard part of at least one of the balloon suction pipeline and the balloon injection pipeline includes parallel parts 32 and 36 parallel to an axis line of the tip hard part, and the tip opening part that extends from the tip parts of th |
