The present invention provides an ultrasonic endoscope in which wiring can be reliably fixed to a wire housing space of an ultrasonic-oscillator housing part, and a method of manufacturing the ultrasonic endoscope. According to the present invention, a wire housing space is encapsulated from the outside by sealing a gap formed between an ultrasonic oscillator and an ultrasonic-oscillator housing part with sealing members. With this configuration, the wire housing space can be sufficiently filled with filling agent for fixing wires in the wire housing space. This achieves an ultrasonic endoscope in which the wires can be reliably fixed to the wire housing space of the ultrasonic-oscillator housing part.
