誘電体セラミックス、誘電体セラミックスの製造方法及び積層セラミックコンデンサ

摘要

A dielectric ceramic whose primary component is an ABO3 compound (A contains Ba and B contains Ti) has a per-layer thickness of approx. 0.5 μm or less, where the volume ratio to all dielectric sintered grains of those whose grain size is in a range of 0.02 μm to 0.15 μm is adjusted to a grain size distribution of 1% to 10%. High dielectric constant and high reliability can be achieved at the same time with the dielectric ceramic.
