Abstract
Better high-temperature load characteristics are obtained in a laminated ceramic capacitor including a dielectric ceramic layer with a thickness of 1 μm or less. The laminated ceramic capacitor includes a plurality of stacked dielectric ceramic layers, a plurality of internal electrode layers, each disposed between dielectric ceramic layers, and external electrodes that are electrically connected to internal electrode layers. In this laminated ceramic capacitor, when the thickness of each dielectric ceramic layer is denoted by tc and the thickness of each internal electrode layer is denoted by te, tc is 1 μm or less, and tc/te is equal to or less than 1.
Claims20
A laminated ceramic capacitor comprising:
- a plurality of stacked dielectric ceramic layers;
- a plurality of internal electrode layers, each of which is disposed between adjacent dielectric ceramic layers;
- and
- a pair of external electrodes electrically connected to different ones of the plurality of internal electrode layers,
- wherein when the average thickness of each dielectric ceramic layer sandwiched between a pair of internal electrodes is tc, the thickness of each internal electrode layer is te, tc is 1 μm or less, and tc/te is equal to or less than 1.
