摘要：
A D-E hysteresis loop of ferroelectrics known in the art has a square shape when the ferroelectrics are a BaTiO.sub.3 single crystal. Such ferroelectrics are used as a non-linear dielectric element of, for example a pulse generating device. The non-linear dielectric element according to the present invention consists of a polycrystal mainly composed of Ba(Ti.sub.0.90-0.98 Sn.sub.0.02-1.00)O.sub.3 and having an average grain diameter of from 10 to 60 .mu.m. The non-linearity is excellent and the temperature dependence of the non-linearity is considerably low.
