发明名称 積層セラミックコンデンサおよび積層セラミックコンデンサの製造方法
摘要 A laminated ceramic capacitor having internal electrodes configured such that Sn is dissolved in Ni, and, in a region of each of the internal electrodes at a depth of 2 nm from a surface thereof facing a ceramic dielectric layer, a CV value representing variation of a Sn/(Ni+Sn) ratio (ratio of number of atoms) is less than or equal to 32%. As a conductive paste for forming the internal electrodes, a conductive paste containing a Ni powder and a tin oxide powder which is represented by SnO or SnO2 and has a specific surface area of more than or equal to 10 m2/g as determined by a BET method is used, or a conductive paste containing a Ni—Sn alloy powder is used, or a conductive paste containing a Ni—Sn alloy powder and a tin oxide powder which is represented by SnO or SnO2 and has a specific surface area of more than or equal to 10 m2/g is used.
