Abstract
A dielectric composition is a barium titanate-based dielectric composition and includes a barium titanate particle including a major axis, a minor axis disposed on the same plane as the major axis, and a vertical axis perpendicular to both the major axis and the minor axis, and a ratio of a length of the major axis to a length of the vertical axis is within a range from 1.5:1 to 30:1.
