Abstract
In a multilayer ceramic capacitor, a positional deviation in a lamination direction between end portions in a width direction intersecting the lamination direction and a length direction, of two of internal electrode layers adjacent to each other in the lamination direction, is about 5 μm or less. A connection ratio N1/N0 at the middle portion thereof, and a connection ratio N2/N0 at the end portion thereof are about 90% or more, respectively, and a difference between N1/N0 and N2/N0 is about 10% or less.
Claims14
A multilayer ceramic capacitor comprising:
- a multilayer body including dielectric layers and internal electrode layers alternately laminated therein;
- and
- external electrodes respectively provided on both end surfaces of the multilayer body in a length direction intersecting a lamination direction, and each connected to the internal electrode layers;
- wherein
- a positional deviation in the lamination direction between end portions in a width direction intersecting the lamination direction and the length direction, of two of the internal electrode layers adjacent to each other in the lamination direction, is about 5 μm or less;
- and
- when a number of all of the internal electrode layers extending to one of the external electrodes is defined as N0, a number of the internal electrode layers connected to the one of the external electrodes in a cross-section extending in the length direction and the lamination direction and passing through a middle portion thereof in the width direction is defined as N1, and a number of the internal electrode layers connected to the one of the external electrodes in a cross-section extending in the length direction and the lamination direction and passing through an end portion thereof in the width direction is defined as N2:
- a connection ratio N1/N0 at the middle portion thereof, and a connection ratio N2/N0 at the end portion thereof are about 90% or more, respectively;
- and
- a difference between the connection ratio N1/N0 and the connection ratio N2/N0 is about 10% or less.
