Dielectric ceramic composition and electronic device

A dielectric ceramic composition comprising:

• a main component expressed by a general formula:
• (Ba1-x-ySrxCay)m(Ti1-zZrz)O3,
• a first subcomponent comprising Mg oxide,
• a second subcomponent comprising at least one oxide selected from oxides of Mn and Cr,
• a third subcomponent comprising R oxide, wherein R is selected from at least one of Y, La Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, and Yb, and
• a fourth subcomponent comprising an oxide including Si,
• wherein the general formula shows
• 0.20≦x≦0.40,
• 0≦y≦0.20,
• 0≦z≦0.30, and
• 0.950≦m≦1.050,
• wherein ratios of the respective subcomponents with respect to 100 moles of said main component are
• the first subcomponent:
• 0.5 to 5 moles (in terms of element),
• the second subcomponent:
• 0.05 to 2 moles (in terms of element),
• the third subcomponent:
• 1 to 8 moles (in terms of element),
• the fourth subcomponent:
• 0.5 to 5 moles (in terms of an oxide or a complex oxide), and
• within a temperature range of −25 to 105° C., a capacitance change rate on the basis of capacitance at 25° C., with respect to slope “a” of a line which shows capacity temperature characteristic on the basis of capacitance at 25° C., is within −15 to +5%, and said slope “a” is −7000 to −3000 ppm/° C.
