PROBLEM TO BE SOLVED: To provide an ultrasonic signal connector of an ultrasonic endoscope having a compact configuration which achieves good routine operability and maintains excellent air-tightness even when the pressure of an inner space is higher than that of the outside. SOLUTION: A waterproof cap 30 covers a group of electric contacts 18 water-tightly. A waterproof cap engaging groove 19 is formed on a contact group attached wall 17 so that the groove and the edge of the waterproof cap engages detachably. In addition, a pressing nail 23 is formed on the outer edge of the contact group attached wall 17 for pressing the edge of an open end of a connector case 14. With such a configuration, when the pressure of an inner space surrounded by a connector case 14 and the contact group arrangement wall 17 becomes higher than that of the outside, the pressing nail regulates an outward expansion of the open end of the connector case 14 due to a pressure difference between the inside and the outside.
