Abstract: An inkjet ink that contains a functional particle having a BET-equivalent particle diameter of 50 to 1000 nm, a rheology-controlling particle having a BET-equivalent particle diameter of 4 to 40 nm, and an organic vehicle. The ink has a viscosity of 1 to 50 mPa·s at a shear rate of 1000 s−1. At a shear rate of 0.1 s−1, the ink has a viscosity equal to or higher than a viscosity η calculated using the following equation: η=(D)2×ρ/104/2+80 [where η is the viscosity (mPa·s) at a shear rate of 0.1 s−1, D is the BET-equivalent particle diameter (nm) of the functional particle, and ρ is the specific gravity of the functional particle].

Abstract: laminated ceramic capacitor which has favorable moisture resistance includes an inner layer section that has dielectric ceramic layers and internal electrodes stacked alternately, and outer layer sections formed outside the inner layer section. The dielectric ceramic layers have a perovskite-type compound including a main constituent containing Ca and Zr, and an additive containing Si and Mn. The average grain size in the dielectric ceramic layers constituting the outer layer sections is smaller than the average grain size in the dielectric ceramic layers constituting the inner layer section. The Si/Mn molar ratio in the dielectric ceramic near the interfaces between the internal electrodes and the dielectric ceramic layers is ≦15.
