The effect of (Ba,Pb)TiO3 particles upon the conductivity of composite solid electrolytes was investigated. When the Pb content was increased, the dielectric constant decreased. At the same time, the degree of conductivity enhancement of the composite increased. It was found that the Pb content of (Ba,Pb)TiO3 had an effect upon the conductivity enhancement, but it had no direct effect upon the dielectric constant.
