MULTILAYER CERAMIC CAPACITOR

摘要

A multilayer ceramic capacitor includes an external electrode on an end surface of a ceramic body to be connected to internal electrodes including a base layer including a sintered metal containing Cu and glass and a Cu plated layer on the base layer. The external electrode includes a principal surface portion disposed on a principal surface of the ceramic body. The Cu metal of the Cu plated layer is present in the base layer to a position of about ⅓ or more of the thickness of the base layer from a surface layer of the external electrode. The metal thickness of the external electrode is about 8.7 μm or more and about 13.9 μm or less.

1. A multilayer ceramic capacitor comprising:
a ceramic body including a plurality of ceramic layers and first and second internal electrodes stacked, the ceramic body including first and second principal surfaces opposed to each other in a height direction, side surfaces opposed to each other in a width direction, and end surfaces opposed to each other in a length direction; and an external electrode including a base layer including metal and glass and a plated layer provided over a surface of the base layer, the external electrode provided over one of the end surfaces and a portion of the first principal surface of the ceramic body, and connected to one of the first and second internal electrodes at the one of the end surfaces; wherein the plated layer includes a Cu plated layer including an outermost surface of the external electrode; and Cu plated materials are present in the base layer to a position of about ⅓ or more of a thickness of the base layer from a surface layer of the external electrode; and the external electrode is about 8.7 μm or more and about 13.9 μm or less in metal thickness on average.
