<P>PROBLEM TO BE SOLVED: To provide a laminated ceramic capacitor which can improve sinterability, can impart a reduction resistance, and also can enhance a relative dielectric constant. <P>SOLUTION: A laminated ceramic capacitor 1 has a plurality of laminated dielectric ceramic layers 2, internal electrodes 3A and 3B arranged between the dielectric ceramic layers, and external electrodes 4A and 4B which are electrically connected to the internal electrodes. The dielectric ceramic layer is formed of a dielectric ceramic composition containing a tungsten bronze type composite oxide as a main component expressed by the compositional formula of (K<SB POS="POST">1-y</SB>Na<SB POS="POST">y</SB>)Sr<SB POS="POST">2</SB>Nb<SB POS="POST">5</SB>O<SB POS="POST">15</SB>(where 0≤y<0.2). Nb of 20 mol% or less in the compositional formula is substituted by a sub-component, and the sub-component includes Mn and at least one element selected from Cr, Co, Fe, Ni, Zn, Mg and Si. <P>COPYRIGHT: (C)2012,JPO&INPIT |
