Abstract
There is provided a multilayer ceramic capacitor, having an internal electrode layerand an interlayer dielectric layerhaving a thickness of 3.5 μm or less, wherein the interlayer dielectric layeris composed of contact dielectric particlescontacting said internal electrode layer and noncontact dielectric particlesnot contacting said internal electrode layer; and when assuming that an average particle diameter of the contact dielectric particlesis D50e and an average particle diameter of the noncontact dielectric particlesis D50d, D50e<0.450 μm and (D50e/D50d)=1.20 to 3.00 (note that 1.20 and 3.00 are excluded) are satisfied, wherein an improvement of a bias characteristic at 85° C. can be expected even when the interlayer dielectric layeris made thin.
