Provided is a laminated ceramic capacitor that can suppress the decrease in insulation resistance after a moisture-resistance loading test. It contains ceramic layers which include: main-phase grains that have a perovskite-type compound containing Ba and Ti and optionally containing Ca, Sr, Zr, and Hf; and secondary-phase grains that have an average grain size of 100 nm or more and have a Si content of 50 mol % or more per grain, the average grain boundary number, represented by (Average Thickness for Ceramic Layers 3)/(Average Grain Size for Main Phase Grains)-1, is greater than 0 and 3.0 or less, and the average grain size for the secondary-phase grains is 1/4 or more of the average thickness for the ceramic layers 3. |
