Title:
積層セラミック電子部品
Document Type and Number:
Japanese Patent JP6578703
Kind Code:
B2
Abstract:
Provided is a multilayer ceramic electronic device which is capable of preventing decrease of the specific permittivity and of showing less drop of capacitance, even when the dielectric grains constituting the dielectric layers become smaller for thinning of the dielectric layers, wherein Dg/Di≥1 is satisfied, in case that “Di” is an average grain size of the first dielectric grains constituting the dielectric layer in the capacitance region and “Dg” is an average grain size of the second dielectric grains in an exterior area.
