Claim 4:
5. An ultrasound transducer comprising:
a flexible board comprising a plurality of signal lines configured to receive and output an electrical signal;
a plurality of piezoelectric devices, each piezoelectric device of the plurality of piezoelectric devices being electrically connected to a respective signal line of the plurality of signal lines, the plurality of piezoelectric devices being aligned in an alignment direction, each piezoelectric device being configured to transmit and receive an ultrasound wave;
a lead extending from each of the plurality of signal lines, each lead protruding from an end portion of the board, each lead electrically connecting the respective signal line to a respective piezoelectric device of the plurality of piezoelectric devices; and
a plurality of sheets, at least a portion of each sheet of the plurality of sheets being arranged on and between adjacent leads in the alignment direction, each sheet having an electrical insulation property;
wherein each lead has a flat plate shape,
each sheet comprises first and second sheets, the first sheet and the second sheet are made of a sheet-shaped insulation material, the first sheet being arranged on a part of a second surface of each lead and the second sheet being arranged on a part of a third surface of each lead, the second surface facing the piezoelectric device, the third surface being opposite to the second surface, and
the first sheet is positioned between adjacent piezoelectric devices.
