Abstract
A multilayer ceramic part of the invention comprises an internal conductor layer and a ceramic layer which are formed by co-firing. The internal conductor layer is formed of an electrical conducting material containing silver as a main component, and the ceramic layer is formed of an yttrium-iron-garnet based oxide magnetic material with silver added thereto. Thus, the multilayer ceramic part can be fabricated in high yields, even when its size is much more smaller than that of a multilayer ceramic part fabricated until now.
