CERAMIC ELECTRONIC COMPONENT

Japanese Patent JP2023106279

A

To provide a ceramic electronic component excellent in reliability and a ceramic electronic component with improved capacity per unit volume.SOLUTION: A ceramic electronic component includes: a main body that includes dielectric layers 111 and internal electrodes 121 and 122; and external electrodes arranged on the main body while being coupled with the internal electrodes. Each dielectric layer includes a plurality of dielectric crystal grains G. For the dielectric layer, the number of dielectric crystal grains per unit thickness of 1 μm is 8 or more. When an average thickness of the dielectric layers is defined as td, td is equal to or less than 0.5 μm. In the main body, the dielectric layers and the internal electrodes are alternately arranged in a lamination direction. The main body includes first and second surfaces opposed to each other in the lamination direction, third and fourth surfaces opposed to each other in a lengthwise direction while being coupled with the first and second surfaces, and fifth and sixth surfaces opposed to each other in a width direction while being coupled with the first to fourth surfaces. The external electrodes are arranged on the third and fourth surfaces. For the ceramic electronic component, the maximum size in the lengthwise direction is equal to or less than 1.76 mm, and the maximum size in the width direction is equal to or less than 0.88 mm.SELECTED DRAWING: Figure 5
