Claim:
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%, wherein the crystal phase area ratio (%)={the area of the crystal phase/(the area of the crystal phase+the area of glass phase area)}×100%).
