Since the end portions of the leads are exposed to this flattened surface of the backing layer, discrete electrodes formed on the back surfaces of transducer elements are electrically connected to these lead end portions. The accuracy of lead arrangement is thus improved by the use of the alignment jig. This reduces alignment errors of leads with respect to the discrete electrodes of the transducer elements.Type: GrantFiled: December 8, 1999Date of Patent: October 30, 2001Assignee: Kabushiki Kaisha ToshibaInventor: Satoru Tezuka
