Abstract
A backing includes a plurality of backing plates that are laminated. Each backing plate includes a lead row and a backing material. Each lead includes a lead wire and an insulating coating. The insulating coating is integrated with the backing material, and an adhesive layer between them does not exist. Short-circuit between the leads may be prevented or reduced by the insulating coating. The backing plate is manufactured by a screen printing method.
Claims3
An ultrasonic probe comprising:
- a vibration element array consisting of a plurality of vibration elements arranged two-dimensionally;
- and
- a backing provided on a rear surface side of the vibration element array and consisting of a plurality of backing plates that are laminated, wherein
- each of the backing plates includes:
- a lead row consisting of a plurality of leads that are electrically connected to the vibration element array;
- and
- a plate main body formed of a backing material, the plate main body including a plurality of grooves that are directly coupled to the plurality of leads without an adhesive layer while accommodating the plurality of leads, and
- each of the leads includes a lead wire and an insulating coating wrapping the lead wire, wherein
- the backing includes an adhesive that bonds the plurality of backing plates to one another and has a lower viscosity than the backing plates, and
- each insulating coating of the leads consists of a material that is different from the adhesive.
