Abstract
A ceramic electronic component includes a multilayer structure having a substantially rectangular parallelepiped shape and including dielectric layers and internal electrode layers that are alternately stacked, the dielectric layers being mainly composed of ceramic, the internal electrode layers being alternately exposed to two edge faces of the multilayer structure opposite to each other, wherein x/y is 0.143 or less where x represents an average concentration of hydrogen in ppm in a capacitance section where the internal electrode layers exposed to one of the two edge faces and the internal electrode layers exposed to the other of the two edge faces are opposed to each other, as measured by secondary ion mass spectrometry (SIMS), and y represents an average concentration of titanium in ppm in the capacitance section, as measured by SIMS at the same time of measuring the average concentration of hydrogen.
