PROBLEM TO BE SOLVED: To improve a yield by suppressing the occurrence of a structural defect due to a thermal stress caused by the difference in thermal expansion ratio between an interior portion and an exterior portion, even when thin-layer and mulilayer of a dielectric layer further progresses. SOLUTION: A laminate ceramic electronic component formed by alternately laminating a dielectric layer and an electrode layer is manufactured in such a way that an interior green sheet containing a dielectric powder and an electrode precursor containing a metallic powder are alternately laminated to form an interior portion, an exterior green sheet is laminated on both sides of the laminate direction of the interior portion to obtain a laminate, and the laminate is baked. In manufacturing the component, a formula 1.00<Rm<SB>b</SB>/Rm<SB>a</SB>≤2.00 is established, where the number of laminates of the interior green sheet is n, the average grain size of the metallic powder contained in the electrode precursor to be arranged from both ends of the laminate direction of the interior portion to mth layer (where, m is 0.05n-0.25n) of each of the ends is Rm<SB>a</SB>and the average grain size of the metallic powder contained in the other electrode precursor is Rm<SB>b</SB>.
