Abstract: Provided is an ultrasound endoscope capable of suppressing image quality deterioration of an ultrasound image and achieving reduction in diameter.
An ultrasound endoscope includes 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. 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 connected to the corresponding electrode pad of the substrate. The plurality of ultrasound transducers are configured in a plurality of drive units to be driven simultaneously. The plurality of signal wires of each first cable bundle are connected to a plurality of electrode pads in each drive unit to configure a signal wire group, and the signal wire group includes at least two kinds or more of signal wires different in length from a distal end of the first cable bundle.

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. The ultrasound endoscope further includes a fixing part that fixes relative positions of the substrate and each first cable bundle.
