Ultrasound endoscope

An ultrasound endoscope comprising:

• an insertion part that includes a distal end part having an ultrasound transducer array in which a plurality of ultrasound transducers are arranged;
• a cable that is inserted into the insertion part;
• and
• a substrate that electrically connects the plurality of ultrasound transducers and the cable, and is disposed in the distal end part,
• wherein the cable has
• a non-coaxial cable that includes a first cable bundle consisting of a plurality of signal wires and a plurality of ground wires, and a first shield layer with which the first cable bundle is coated, and
• an outer coat with which a second cable bundle consisting of a plurality of the non-coaxial cables is coated,
• the substrate includes a plurality of electrode pads connected to the plurality of ultrasound transducers, respectively,
• each first cable bundle is individually led out from the cable, and each signal wire of the first cable bundle is led out and electrically bonded to the corresponding electrode pad of the substrate, and
• a fixing part that fixes relative positions of the substrate and each first cable bundle, and a filler layer that covers the substrate, the first cable bundle and the fixing part, are provided.
