MONOLITHIC CERAMIC ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING THE SAME

摘要

A monolithic ceramic electronic component having outer electrodes that include an inorganic substance containing at least Si, a crystal phase C containing at least Si, Ti, and Ba at the interfaces to a ceramic layer in peripheral end portions of the outer electrodes. A value of the crystal phase area ratio indicating the relationship between the area of the crystal phase C and the area of a glass phase G, which are formed at the interface to the ceramic layer, in a region within 5 μm from the peripheral end portion of the outer electrode is within a range of 75% to 98%.

1. A monolithic ceramic electronic component comprising:
a monolithic ceramic element having alternately stacked inner electrodes and ceramic layers; and at least a pair of outer electrodes disposed on the monolithic ceramic element and electrically connected to respective sets of the inner electrodes, wherein the outer electrode includes an inorganic substance containing at least Si, peripheral end portions of the outer electrodes include a crystal phase containing at least Si, Ti, and Ba at an interface to the ceramic layer of the monolithic ceramic element, and a value of a crystal phase area ratio indicating a relationship between an area of the crystal phase and an area of a glass phase at the interface to the ceramic layer, in a region within 5 μm from the peripheral end portion of the outer electrode, is within a range of 75% to 98%.
