Abstract
A multi-layer ceramic capacitor has a structure where the dispersion, nd, of average grain size of the dielectric grains constituting the dielectric layer (a value (D90/D10) obtained by dividing D90 which is a grain size including 90% cumulative abundance of grains by D10 which is a grain size including 10% cumulative abundance of grains) is smaller than 4.
