Abstract
In an embodiment, a multilayer ceramic capacitor 10 has a capacitor body 11 having a first face f1 and a second face f2 in a length direction, a third face f3 and a fourth face f4 in a width direction, a fifth face f5 and a sixth face f6 in a height direction, and a first tapering face f5a between face f1 and face f5 and a second tapering face f5b between face f2 and face 5f; a first external electrode 12 that has a first part 12a along face f1, a second part 12b along face f5, and continuously a third part 12c along face f5a; and a second external electrode 13 that has a first part 13a along face f2, a second part 13b along face f5, and continuously a third part 13c along face f5b.
Claims14
A multilayer ceramic capacitor comprising:
- (1) a capacitor body having a first face and a second face that are facing each other in a length direction, a third face and a fourth face that are facing each other in a width direction, and a fifth face and a sixth face that are facing each other in a height direction, as well as a built-in capacitive part constituted by multiple first internal electrode layers and multiple second internal electrode layers stacked alternately with dielectric layers in between;
- (2) a first external electrode having a first part along the first face, and a second part along the fifth face, of the capacitor body, where ends of the multiple first internal electrode layers are connected to the first part, respectively;
- and
- (3) a second external electrode having a first part along the second face, and a second part along the fifth face, of the capacitor body, where ends of the multiple second internal electrode layers are connected to the first part, respectively;
- wherein the capacitor body has, over an entire width direction and at a position adjacent to the first face, a first tapering face that decreases a height-direction dimension of the first face, and also has, over an entire width direction and at a position adjacent to the second face, a second tapering face that decreases a height-direction dimension of the second face;
- wherein the first external electrode has, between the first part and the second part, a third part along the first tapering face of the capacitor body;
- wherein the second external electrode has, between the first part and the second part, a third part along the second tapering face of the capacitor body;
- and
- wherein the first external electrode and second external electrode are each shaped in such a way that, when an exterior face of the second part of the first external electrode and an exterior face of the second part of the second external electrode are each contacting a virtual plane, a first clearance that narrows from an outer side toward an inner side is formed between an exterior face of the third part of the first external electrode and the virtual plane, while a second clearance that narrows from an outer side toward an inner side is formed between an exterior face of the third part of the second external electrode and the virtual plane.
