Non-magnetic ceramics and ceramic multilayer parts
 The invention provides a nonmagnetic ceramic comprising 5% to 40% by weight of .alpha.-quartz and 5% to 60% by weigth of zinc silicate dispersed in 35% to 75% by weight of borosilicate glass as a matrix, the borosilicate glass having SiO.sub.2 and B.sub.2 O.sub.3 contents: SiO.sub.2 =70 to 90% by weight and B.sub.2 O.sub.3 =10 to 30% by weight. Using the nonmagnetic ceramic, multilayer ceramic inductors are obtained. When the ceramic is used as ceramic multilayer parts having an inductor section, it has a low dielectric constant and good characteristics in the high-frequency region, allows for low-temperature firing enabling the use of silver electrodes, prevents chip deformation and crack occurrence upon sintering, and provides a higher mechanical strength.
