Abstract:
In a multilayer ceramic electronic component, a ferrite ceramic material defining a base layer includes bismuth. Meanwhile, surface layers arranged on main surfaces of the base layer have a composition that is substantially free from bismuth. The surface layers have a zinc content greater than that of the base layer. This results in satisfactory sinterability even when bismuth is included in the surface layers.
