Title:
LAMINATE CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2015/005306
Kind Code:
A1
Abstract:
[Problem] 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. [Solution] 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
