Claim 0:
1. A dielectric elastomer transducer comprising:
a dielectric elastomer layer; and
a pair of electrode layers sandwiching the dielectric elastomer layer, wherein
the electrode layers contain a binder and carbon black, the carbon black having a particle size distribution as measured by dynamic light scattering in which not less than 95% falls in a range of 0.15 to 8.0 μm, the carbon black having a particle size as measured by laser scattering ranging from 0.4 to 50 μm, and the particle size distribution of the carbon black as measured by dynamic light scattering having a first peak that falls in a first range of 0.15 to 1.0 μm and a second peak that falls in a second range of 1.0 μm to 8.0 μm.
