PROBLEM TO BE SOLVED: To provide an ultrasonic endoscope which makes wiring formed on flexible substrate hardly disconnectable and is highly durable even if the flection action of a bending section is repeated. SOLUTION: The flexible substrate 40 are divided to a plurality in parallel by forming the width of the flexible substrates 40 to the width suitable for connecting to an ultrasonic probe 4 near the distal end and formed the substrates wider than the width near the distance end in the segments existing within the bending section 2.
