Abstract
A ceramic electronic component includes a dielectric layer and an electrode layer. The dielectric layer contains a plurality of ceramic particles and grain boundary phases present therebetween. A main component of the ceramic particles is barium titanate. An average thickness of the grain boundary phases is 1.0 nm or more. A thickness variation σ of the grain boundary phases is 0.1 nm or less.
