Abstract
A condenser including a dielectric material exhibiting a ferroelectric phase wherein the dielectric constant-temperature characteristic of the condenser exhibits hysteresis loss of not more than 5% is provided. The dielectric constant-temperature characteristics are varied by regulating the particle diameter of the crystal and by providing an electrode material which reduces the loss. Hysteresis loss may also be reduced by including an oxide of a rare earth element or a metallic element of Group Va of the Periodic Table into a barium titanate dielectric component system.
