1. An ultrasound endoscope comprising:
a distal end part having an ultrasound transducer array in which a plurality of ultrasound transducers are arranged;
an insertion part which is continuously connected to the distal end part;
a first cable whose distal end side is connected to the distal end part, and wherein the first cable is configured to be inserted into the insertion part;
a substrate configured to electrically connect the plurality of ultrasound transducers and the distal end side of the first cable;
a second cable which is disposed on a proximal end side from the first cable and wherein the proximal end side of the second cable is configured to be electrically connected to a connector substrate; and
a relay substrate configured to electrically connect the proximal end side of the first cable and a distal end side of the second cable, the relay substrate provided in a part other than the distal end part,
wherein the first cable comprises:
a plurality of first non-coaxial cables; and
an outer coat which coats the plurality of the first non-coaxial cables,
each of the plurality of first non-coaxial cables comprises:
a first cable bundle including a plurality of signal wires and a plurality of ground wires; and a first shield layer configured to coat the first cable bundle,
the substrate includes a plurality of electrode pads connected to the plurality of ultrasound transducers, respectively,
the electrode pads and the signal wires of the first cable bundles are electrically connected to form a plurality of first electrical bonded portions,
the plurality of first electrical bonded portions are collectively disposed for each first cable bundle,
the relay substrate includes:
a plurality of first cable-side electrode pads corresponding to the signal wires included in the first cable bundles; and
a plurality of second electrical bonded portions in which the first cable-side electrode pads
and the signal wires of the first cable bundles are connected, the plurality of second electrical bonded portions are collectively disposed for each first cable bundle, and
the relay substrate comprises a plurality of separate substrates arranged along a longitudinal axis direction of the insertion part, in which adjacent separate substrates are electrically connected to each other.
