Claim 0:
1. 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 the board includes an arc portion with an arc shape,
each lead is arranged to protrude from a distal end of the arc portion,
the plurality of piezoelectric devices are aligned along the arc portion, and
surfaces of at least two adjacent sheets of the plurality of sheets are in contact with each other, the surfaces intersecting the alignment direction of the plurality of piezoelectric devices.
