Abstract
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%.
