Dielectric ceramic and ceramic capacitor using the same

Abstract

A dielectric ceramic having: a rutile compound represented by (TixSn1−x)O2 as a main constituent; and Nb, wherein 0.40≤x≤0.60, and in a sectional view the dielectric ceramic includes: a Ti-rich phase region in which A is 0.55 or more, a Sn-rich phase region in which B is 0.55 or more, A=(Ti content (atom %))/(total content of Ti and Sn (atom %)), B=(Sn content (atom %))/(total content of Ti and Sn (atom %)), 0.005 mol %≤y≤0.020 mol %, 16 nm≤DTi≤20 nm, 15 nm≤DSn≤19 nm, wherein y (mol %) is a content of Nb with respect to 100 mol % of a content of the rutile compound, DTi (nm) is an average size of the Ti-rich phase region, and DSn (nm) is an average size of the Sn-rich phase region.
