Abstract
A dielectric ceramic enabling low-temperature firing and exhibiting good dielectric characteristics, and a stack ceramic electronic component using the same are provided. The dielectric ceramic containing (Ba1-x-yCaxSry)m(Ti1-zZrz)O3 (1.005≦m≦1.2, 0≦x+y≦0.2, and 0≦z≦0.2) as a major component and an amount of Bi relative to 100 parts by mol of the major component which is 1.0 part by mol or more and 40 parts by mol or less.
