Title:
超音波トランスデューサ、超音波プローブおよび超音波トランスデューサの製造方法
Document Type and Number:
Japanese Patent JP5738671
Kind Code:
B2
Abstract:
The purpose is to provide an ultrasonic transducer and ultrasonic probe without the complexity of the manufacturing process of a non-conductive acoustic matching layer while ensuring the conductive path. In the non-conductive acoustic matching layer comprising the first surface of the electrode side and the second surface of the opposite side of the piezoelectrics, a plurality of first grooves leading up to the mid-way point between the first surface and the second surface are arranged on each of the first surfaces of the non-conductive acoustic matching later in response to the arrangement of sound elements. Moreover, each of the second surfaces is provided with the plurality of second grooves leading up to at least the mid-way point from the second surface, intersecting the first grooves.
