Claim Text:
1. A method for manufacturing a laminated ceramic capacitor, the method comprising: preparing a main constituent powder containing, as a main constituent thereof, a perovskite-type compound containing Ca and Zr; preparing a Si compound, a Mn compound, an Al compound; mixing the main constituent powder, the Si compound, the Mn compound, and the Al compound to form a ceramic slurry; forming ceramic green sheets from the ceramic slurry; stacking the ceramic green sheets and internal electrode layers to obtain an unfired laminated body; and firing the unfired laminated body to obtain a laminated body with internal electrodes between dielectric layers, wherein, for respective elements of the dielectric layers, when the total of Zr is regarded as 100 parts by mol, the total content (100×m) of Ca meets 1.002≦m≦1.100 in terms of parts by mol, the Si content n meets 0.5≦n≦10 in terms of parts by mol, the Mn content u meets 0.5≦u≦10 in terms of parts by mol, and the Al content w meets 0.02≦w≦4 in terms of parts by mol, m and n satisfying −0.4≦100(m−1)−n≦3.9.
