Ultrasound transducer, ultrasound endoscope, and method of manufacturing ultrasound transducer

An ultrasound transducer, comprising:

• an acoustic matching layer;
• a plurality of piezoelectric elements provided on the acoustic matching layer;
• a plurality of blocks, each provided at at least one end of a corresponding piezoelectric element of the plurality of piezoelectric elements in an elevation direction of the plurality of piezoelectric elements, each of the plurality of blocks being provided on the acoustic matching layer;
• and
• a substrate arranged between each block and the corresponding piezoelectric element in the elevation direction;
• wherein the acoustic matching layer is configured to have an arc-shape with the plurality of piezoelectric elements arranged on an inside of the arc-shape;
• and
• during the acoustic matching layer being bent into the arc-shape, a block of the plurality of blocks and an adjacent block of the plurality of blocks contact to prevent corresponding adjacent piezoelectric elements of the plurality of piezoelectric elements from contacting.
