发明名称 Dielectric ceramic composition and electronic device
摘要 A dielectric ceramic composition comprising a predetermined main component and a fifth subcomponent including an oxide of A (note that A is at least one king selected from a cation element group having an effective ionic radius of 0.065 nm to 0.085 nm at the time of 6 coordination); and the dielectric ceramic composition comprises a plurality of crystal grains including Ca elements and, when assuming that an average value of a concentration of entire Ca exiting in said respective crystal grains is grain Ca concentration, at least unevenness exists in said grain Ca concentration between said crystal grains and it is 5% or higher in a CV value.
