Title:
An ultrasonic transducer, an ultrasound probe, and an ultrasonic imaging apparatus
Document Type and Number:
Japanese Patent JP6277899
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic transducer capable of suppressing ripple generation even when ultrasonic waves of broader band are output, an ultrasonic probe, and an ultrasonic imaging apparatus.SOLUTION: An ultrasonic transducer 100 is so configured that, to a piezoelectric material layer 130 partitioned so as to constitute a piezoelectric element by grooves 140, 141, an integrated acoustic matching layer 160 is bonded in a planar direction, and an integrated acoustic lens 170 is bonded to the acoustic matching layer 160 through an adhesive layer 180. The adhesive layer 180 is a layer of a silicone adhesive. The thickness of the adhesive layer 180 is equal to or less than 10 μm.SELECTED DRAWING: Figure 1
