摘要： In an ultrasonic endoscope, excessive temperature rise due to heat generated from ultrasonic transducers and/or an image pickup device is prevented. The ultrasonic endoscope includes: an ultrasonic transducer part including plural ultrasonic transducers for transmitting and receiving ultrasonic waves, and a backing material provided on a back of the plural ultrasonic transducers and having plural signal terminals provided on a surface opposite to the plural ultrasonic transducers; a signal line holding part including a highly heat conducting filler filling a space holding a group of shield lines electrically connected to the ultrasonic transducers via the plural signal terminals, and coupled to the backing material; and a highly heat conducting layer provided in contact with the signal line holding part, and thereby coupled to the signal line holding part.
