Abstract
A ceramic electronic component includes a stack including ceramic layers and internal electrodes stacked alternately, and external electrodes provided on a surface of the stack and electrically connected to the internal electrodes. The internal electrodes include a melting trigger portion that melts earlier than any other portion. The ceramic layer adjacent to the internal electrode including the melting trigger portion includes a cavity. The cavity is provided at a position at which the cavity overlaps the melting trigger portion at least partially in a stacking direction of the internal electrodes. The cavity is open on a melting trigger portion side. A surface of at least one of the stack and the external electrodes is provided with an identifier that serves as a marker indicating use of the ceramic electronic component with the cavity vertically below the melting trigger portion.
