ULTRASONIC PROBE AND METHOD OF MANUFACTURING THE ULTRASONIC PROBE

摘要

An ultrasonic probe includes: a piezoelectric transducer which generates ultrasonic waves when voltage is applied to the piezoelectric transducer; and an acoustic matching layer for matching acoustic impedances between the piezoelectric transducer and a subject. The acoustic matching layer includes a sintered layer having, across a surface of the sintered layer, a plurality of microscopic pores formed by sintering a composite including a bonding material and metal nanoparticles each having a size of one micron or less.
