## Abstract

An ultrasound transducer module includes: an ultrasound transducer configured to transmit and receive ultrasound; a substrate electrically connected with the ultrasound transducer and including a first wiring pad at a portion different from a connection portion with the ultrasound transducer; and a casing that includes an accommodation hole for accommodating the ultrasound transducer and the substrate and that includes a holding hole continued to the accommodation hole and capable of holding a portion of the substrate, the casing having a plurality of electrode pads provided on an outer surface of the casing and having a plurality of second wiring pads provided in the holding hole, each second wiring pad being electrically connected with a corresponding electrode pad among the plurality of electrode pads, and electrically connected with the first wiring pad.

## Claims

### Claim 1

An ultrasound endoscope comprising:
an insertion portion having a distal end with an ultrasound transducer module, the ultrasound transducer module comprising:
an ultrasound transducer configured to transmit and receive ultrasound;
a substrate electrically connected with the ultrasound transducer, the substrate including a first wiring pad and a connection portion for connecting the substrate to the ultrasound transducer, the first wiring pad and the connection portion being arranged on the substrate at different positions from each other; and
a casing configured to accommodate the ultrasound transducer and the substrate therein, the casing comprising:
an accommodation hole formed in the casing for accommodating the ultrasound transducer and the substrate,
a holding hole by which the substrate is partially held, the holding hole being continuous with the accommodation hole,
a plurality of electrode pads provided on an outer surface of the casing, and
a plurality of second wiring pads provided in the holding hole, each second wiring pad being electrically connected with a corresponding electrode pad among the plurality of electrode pads, and electrically connected with the first wiring pad;
the insertion portion being configured to be inserted into a subject; and
a cable electrically connected to the ultrasound transducer module.

### Claim 2 (depends on 1)

The ultrasound endoscope according to claim 1,
wherein the holding hole has a groove configured to partially accommodate the substrate therein, the groove being formed on a surface of the accommodation hole, and
a surface of the second wiring pad, on a side that comes in contact with the first wiring pad, is a portion of a surface of the holding hole.

### Claim 3 (depends on 1)

The ultrasound endoscope according to claim 1,
wherein the accommodation hole extends in a direction orthogonal to an axial direction of the casing, the direction being a depth direction of the accommodation hole, and
the holding hole extends from the accommodation hole in a direction perpendicular to the axial direction of the casing.

### Claim 4 (depends on 1)

The ultrasound endoscope according to claim 1,
wherein the accommodation hole extends in a direction orthogonal to an axial direction of the casing, the direction being a depth direction of the accommodation hole, and
the holding hole extends from the accommodation hole in the axial direction of the casing.

### Claim 5 (depends on 1)

The ultrasound endoscope according to claim 1, wherein the plurality of second wiring pads are electrically connected with the corresponding electrode pad via an internal portion of the casing.

### Claim 6 (depends on 1)

The ultrasound endoscope according to claim 1,
wherein the ultrasound transducer is provided at the distal end of the insertion portion to be inserted into the subject, and is configured to transmit and receive the ultrasound on a plane including a longitudinal axis of the insertion portion and parallel to the longitudinal axis,
the substrate is provided on a side opposite to a surface of the ultrasound transducer on which the ultrasound is transmitted and received.
