Claim Text:
1. A method for manufacturing a ceramic electronic component including a ceramic body including first and second principal surfaces, first and second side surfaces, and first and second end surfaces, a first internal electrode provided in the ceramic body, the first internal electrode extending in a direction from the first end surface, a second internal electrode provided in the ceramic body to be opposed to the first internal electrode with a ceramic layer interposed therebetween, the second internal electrode extending in the direction from the second end surface, a first external electrode provided on the first end surface and connected to the first internal electrode, and a second external electrode provided on the second end surface and connected to the second internal electrode, wherein the ceramic body includes a cross-linked section penetrating through the first internal electrode, and providing a cross-linkage for the ceramic layers adjacent with the first internal electrode interposed therebetween, the first internal electrode includes a first opposed section opposite to the second internal electrode with the ceramic layer interposed therebetween and a first extraction section located closer to the first end surface than the first opposed section, the first extraction section being connected to the first external electrode, and the cross-linked section is provided in the first opposed section and the first extraction section, the method comprising: a step of preparing a green sheet laminated body by stacking a plurality of ceramic green sheets including a ceramic green sheet for forming the ceramic body, the ceramic green sheet including, on a surface thereof, a conductive paste layer for forming the first or second internal electrode; and a firing step of preparing the ceramic body by firing the green sheet laminated body; wherein in the firing step, the green sheet laminated body is heated at a rate such that a surface layer of the green sheet laminated body is fired earlier than a central section of the green sheet laminated body, and a number of the cross-linked sections per unit area formed in the first extraction section is less than a number of the cross-linked sections per unit area formed in the first opposed section; and the number of the cross-linked sections per unit area in the first extraction section is about ⅕ or less of the number of the cross-linked sections per unit area in the first opposed section.
