Patent ID: 11996245

Abstract:
A ceramic electronic component includes: a ceramic body including main surfaces perpendicular to a first axis and end surfaces perpendicular to a second axis; and external electrodes covering the end surfaces and extending from the end surfaces to the main surfaces. The external electrode includes a surface layer portion including a Sn plating layer, and an inner layer portion including a Ni plating layer adjacent to the Sn plating layer and including rounded inner end portions on the main surfaces. In a cross-section perpendicular to a third axis, a ratio t2/t1 is 0.4 or more, where t2 is a thickness in the first axis direction of a portion where an inclination of a tangent line of an outer surface of the inner end portion to each main surface is 45°, and t1 is a maximum thickness in the first axis direction of the inner layer portion on each main surface.
