An ultrasound endoscope includes an insertion part including a distal end part having an ultrasound transducer array of ultrasound transducers, a cable inserted into the insertion part, and a substrate, including electrode pads, that electrically connects the ultrasound transducers and the cable, and is disposed in the distal end part. The cable has a non-coaxial cable including a first cable bundle consisting of signal wires and 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 the non-coaxial cables is coated. 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. The ultrasound endoscope further includes a fixing part that fixes relative positions of the substrate and each first cable bundle.

Ultrasound endoscope

An ultrasound endoscope includes an insertion part including a distal end part having an ultrasound transducer array, a cable inserted into the insertion part, and a substrate, including electrode pads connected to the ultrasound transducers, respectively, that electrically connects the ultrasound transducers and the cable, and is disposed in the distal end part. The cable has a non-coaxial cable including a first cable bundle consisting of signal wires and ground wires, a first shield layer coating the first cable bundle, and an outer coat coating a second cable bundle consisting of the non-coaxial cables. Each first cable bundle is individually led out from the cable, and each signal wire is electrically connected to the corresponding electrode pad. The ultrasound transducers are configured in drive units and driven simultaneously. A signal wire group includes at least two kinds of signal wires different in length from a distal end of the first cable bundle.
