Claim Text:
1. A method for manufacturing a ceramic electronic component having a magnetic section containing at least Fe, Ni, and Zn and an internal conductor containing Cu as a main constituent, the internal conductor being buried in the magnetic section, the method comprising the steps of firing an unfired laminated body having an internal conductor material to serve as the internal conductor after the firing, the internal conductor material being buried in a magnetic material to serve as the magnetic section after the firing, the firing being at a predetermined temperature rising rate X (° C./min) and oxygen partial pressure Y (Pa), and when the temperature rising rate and the oxygen partial pressure are respectively indicated on an x axis and a Y axis, the firing being carried out under a maximum condition indicated by a region surrounded by (X, Y)=A (50, 0.05), B (1000, 0.05), C (1000, 0.01), D (1500, 0.01), E (1500, 0.001), F (2000, 0.001), G (2000, 100), H (1500, 100), I (1500, 50), J (1000, 50), K (1000, 10), and L (50, 10).
