Abstract
A dielectric material for a transducer is manufactured from a composition that includes metal oxide particles having hydroxy groups, a rubber polymer having a functional group capable of reacting with an epoxy group, a bisphenol type epoxy resin, both ends of which have an epoxy group, and a cross-linking agent. In the dielectric material for a transducer, the metal oxide particles are bound to the rubber polymer via the bisphenol type epoxy resin. A transducer includes a dielectric layer made of the dielectric material for a transducer and a plurality of electrodes arranged with the dielectric layer interposed therebetween.
