摘要： An ultrasonic probe for use in the ultrasonic endoscope including a damping layer arranged on a rear surface of an ultrasonic vibrating element for absorbing an undesired ultrasonic wave emitted from the rear surface of the vibrating element, an insulating layer and a conductive housing. A matching coil for improving the efficiency of the vibration of the ultrasonic vibrating element is formed as an air-core type and is embedded within the damping layer or the insulating layer such that the undesired ultrasonic wave is passed through a hollow central space of the air-core type matching coil and is effectively absorbed by the damping layer, so that the damping function of the damping layer is not affected by the matching coil.
