Multilayer ceramic capacitor |
摘要 |
There is provided a multilayer ceramic capacitor 1, having an internal.electrode layer 3 and an interlayer dielectric layer 2 having a thickness of 3.5 µm or less, wherein the interlayer dielectric layer 2 is composed of contact dielectric particles 2a contacting said internal electrode layer and noncontact dielectric particles 2b not contacting said internal electrode layer; and when assuming that an average particle diameter of the contact dielectric particles 2a is D50e and an average particle diameter of the noncontact dielectric particles 2b is 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 layer 2 is made thin.
