摘要

Provided is a composition for an acoustic wave probe, said composition containing a polysiloxane mixture comprising: a polysiloxane having a vinyl group; a polysiloxane having at least two Si-H groups in the molecular chain thereof; and at least one type of inorganic compound particles. The inorganic compound particles have an average primary particle size of less than 25 nm, and are selected from the group consisting of magnesium oxide, titanium oxide, iron oxide, zinc oxide, zirconium oxide, barium oxide, tin oxide and ytterbium oxide. With this composition for an acoustic wave probe, it is possible to greatly enhance the hardness and mechanical strength (tensile fracture strength, tensile fracture elongation, tear strength and wear resistance) of silicone resins while keeping acoustic wave attenuation low. Moreover, the present invention is capable of enhancing the sensitivity of ultrasonic probes, photoacoustic wave measurement devices and ultrasonic endoscopes using a cMUT as a transducer for ultrasonic diagnosis.
