Ceramic electronic component
View Patent ↗A ceramic electronic component 100 includes a ceramic body 1 in which internal electrodes containing a metal component is buried, and a pair of terminal electrodes 3 provided to cover both end surfaces 11 of the ceramic body to which the internal electrodes are exposed. Each of the terminal electrodes 3 has a first electrode layer and a second electrode layer formed by baking a conductive green sheet from a side close to the ceramic body 1 . The second electrode layer contains the metal component diffused from the internal electrodes.
