摘要： An electronic component includes a first external electrode disposed on a first end surface and a second external electrode disposed on a second end surface. The first external electrode includes a first conductive layer including ceramic particles. The second external electrode includes a second conductive layer including ceramic particles. An end portion of a first internal electrode is located inside the first conductive layer. The electronic component includes little or no cracks and has a low equivalent series resistance (ESR).

摘要： A ceramic electronic component includes a stack including ceramic layers and internal electrodes stacked alternately, and external electrodes provided on a surface of the stack and electrically connected to the internal electrodes. The internal electrodes include a melting trigger portion that melts earlier than any other portion. The ceramic layer adjacent to the internal electrode including the melting trigger portion includes a cavity. The cavity is provided at a position at which the cavity overlaps the melting trigger portion at least partially in a stacking direction of the internal electrodes. The cavity is open on a melting trigger portion side. A surface of at least one of the stack and the external electrodes is provided with an identifier that serves as a marker indicating use of the ceramic electronic component with the cavity vertically below the melting trigger portion.

摘要： A method to produce a multilayer ceramic electronic component includes forming supports by an ink jet printing method to produce a green multilayer ceramic capacitor. A green ceramic layer and outer electrodes of the multilayer ceramic electronic component are formed by the ink jet printing method while the supports define peripheries of the green ceramic layer and the outer electrodes. When fired, the green multilayer ceramic electronic component is converted to a sintered multilayer ceramic electronic component, and the supports disappear by heating.

摘要： In an electronic component, a first outer electrode includes a first conductive layer provided on a first end surface. A second outer electrode includes a second conductive layer provided on a second end surface. A first inner electrode passes through the first conductive layer. A second inner electrode passes through the second conductive layer.
