Abstract
Dielectric layers are prepared using a dielectric material that contains a ceramic powder having Ba, Ti, and additive element X which is solid-solubilized and is at least one element selected from the group consisting of Mo, Ta, Nb, and W, wherein the standard deviation of the ratio of the peak intensity of the additive element X (XKα) measured by STEM-EDX, and the sum of the peak intensity of the Ti and peak intensity of the Ba (BaLα+TiKα) measured by STEM-EDX, is less than 10.5% of the average ratio as measured at a total of five points including the three points that divide the maximum diameter of one grain of the ceramic powder into four equal parts, and two excluding the center point of the three points that divide the diameter crossing at right angles with the maximum diameter at its center point, into four equal parts.
