SOUND DAMPING MEMBER AND METHOD FOR PRODUCING SOUND DAMPING MEMBER, ULTRASONIC PROBE, AND ULTRASONIC DIAGNOSIS DEVICE

摘要

A sound damping member (21) is equipped with a sound damper (211) made of a polymer material, and the polymer material of the sound damper (211) contains a plurality of metal fibrous conductors (212) that extend in one predetermined direction and function as a lead wire while adjusting the acoustic impedance. A method for producing the sound damping member (21) comprises a step of coating one major surface of a substrate on which a plurality of growth nucleus are formed with a resin in flowing state into which metal powder conductor is mixed, and a step of curing the resin after applying a magnetic field in the direction normal to the major surface. With such an arrangement, conductor wires are provided onto the sound damping member (21) while reducing irregularities of the sound damping material (21). Furthermore, an ultrasonic probe and an ultrasonic diagnosis device equipped with such a sound damping material (21) can be provided.
