Abstract
To provide a laminate ceramic capacitor which can improve flexural strength without providing, in the main body of the capacitor, a dummy electrode layer or metal layer which does not contribute to capacitance formation. The capacitor main body (11) of this laminate ceramic capacitor (10) has ceramic protective units (11a), capacitance forming units (11b) comprising multiple inner electrode layers (11b1) laminated with ceramic layers (11b2) interposed therebetween, and a ceramic non-capacitance forming unit (11c), and these are arranged from one side towards the other side in the lamination direction in the order protective unit (11a), capacitance forming unit (11b), non-capacitance forming unit (11c), capacitance forming unit (11b) and protective unit (11a). Defining T2 as the thickness of the protective units (11a) in the lamination direction, T3 as the thickness of the capacitance forming units (11b) in the lamination direction, and T4 as the thickness of the non-capacitance forming unit (11c) in the lamination direction, the relation T2<T3<=T4 holds for T2-T4.
Description
technical field [0001] The present invention relates to laminated ceramic capacitors. Background technique [0002] A laminated ceramic capacitor generally includes a capacitor body having a laminated structure and external electrodes respectively provided at opposite ends of the capacitor body. The capacitor main body includes: a capacitance forming portion in which a plurality of internal electrode layers are laminated with ceramic layers interposed therebetween; and ceramic protection portions disposed on both sides of the capacitance forming portion in a stacking direction. In addition, some edges of the plurality of internal electrode layers are connected to one external electrode, and edges of the remaining part are connected to the other external electrode. [0003] Such multilayer ceramic capacitors require bending strength corresponding to stresses received during mounting on a circuit board or the like, thermal shock after mounting, and the like. In addition, the...
