Patent ID: 8383535

Claim:
A multilayer ceramic capacitor, comprising: a capacitor body in which dielectric layers and internal electrode layers are alternately layered; and an external electrode formed on an end surface of the capacitor body where the internal electrodes are exposed, wherein two dielectric layers of the dielectric layers sandwiching one of the internal electrode layers and disposed on both side of the internal electrode layer is formed together with a dielectric bonding member which is arranged such that the dielectric bonding member penetrates part of the internal electrode layer, the dielectric layers are made of a dielectric ceramic which comprises a main crystal phase containing barium titanate as a main crystal component, having a crystal structure mainly comprising a cubic system, having an average grain size of crystal grains constituting the crystal phase in a range of 0.05 to 0.2 μm, and made of a dielectric ceramic comprising ytterium, manganese, magnesium and ytterbium, the dielectric bonding member is made of a dielectric ceramic which contain the same component as the main crystal phase of the dielectric ceramic constituting the dielectric layers, and with respect to one mole of barium, elements calculated by melting and dissolving the multilayer ceramic capacitor in acid are: yttrium equivalent to 0.0014 to 0.03 mole of YO 3/2 ; manganese equivalent to 0.0002 to 0.045 mole of MnO; magnesium equivalent to 0.0075 to 0.04 mole of MgO; and ytterbium equivalent to 0.025 to 0.18 mole of YbO 3/2 .
