Claim:
1. A method for manufacturing a ceramic laminated body, the method comprising: providing a plurality of unfired ceramic dielectric layers containing a ceramic material powder; providing a plurality of unfired internal electrode patters, the plurality of unfired internal electrode patters being in the form of a conductive paste containing a Sn constituent blended common material, the Sn constituent blended common material containing a Sn constituent blended with a ceramic material which has a same composition as that of the ceramic material powder of the unfired ceramic dielectric layers; alternately stacking the plurality of unfired ceramic dielectric layers and the plurality of unfired internal electrode patterns so as to form an unfired ceramic laminated body; and firing the unfired ceramic laminated body at 1200° C. for 20 minutes after increasing the temperature at a rate of temperature increase of 20° C./min in a reducing atmosphere of H wherein the internal electrodes contain Ni and Sn, 75% or more of a first region extending to a depth of 20 nm from a surface of an internal electrode opposed to a fired ceramic dielectric layer of the plurality of alternately stacked fired ceramic dielectric layers and internal electrodes has a first molar ratio of Sn to a total amount of Sn and Ni of 0.001 or more, and 40% or less of a second region extending from the depth of 20 nm or more from the surface of the internal electrode in a thickness direction of the internal electrode has a second molar ratio of Sn to the total amount of Sn and Ni of 0.001 or more.
