The invention provides a ceramic electronic component provided with an external electrode capable of relieving mechanical stress and thermal stress from the outside in a mounted state of the ceramic electronic component. The external electrode includes: a burning electrode layer (12) including a conductive metal and glass; and a plating film provided on the surface of the fired electrode layer (12), the fired electrode layer (12) including: a metal portion (17) including a conductive metal; and a glass part (18) which is distributed in a state of being in contact with the metal part (17) and contains glass. The glass section (18) is provided with a crack (19) that starts from the interface between the metal section (17) and the glass section (18) and faces the inside of the glass section (18). The cracks (19) function so that mechanical stress and thermal stress from the outside are relieved without substantially impeding the compactness of the fired electrode layer (12), and thus the ceramic electronic compo
