  • Publication number: 20240112863
    Abstract: An electronic component includes: a first internal electrode provided in an element body; a second internal electrode provided in the element body; a third internal electrode provided in the element body and drawn out to a first side surface; and a fourth internal electrode provided in the element body and drawn out to a second side surface. The third internal electrode and the fourth internal electrode are electrically connected to each other through an external connection conductor formed on at least the first side surface and the second side surface. In a first direction, the first internal electrode faces the third internal electrode without facing the second internal electrode and the fourth internal electrode. In the first direction, the second internal electrode faces the fourth internal electrode without facing the first internal electrode and the third internal electrode.

  • Patent number: 11710599
    Abstract: A ceramic electronic device includes an element body and an external electrode. The element body is formed by laminating a ceramic layer and an internal electrode layer. The external electrode is electrically connected to at least one end of the internal electrode layer. The external electrode includes a baked electrode layer. The baked electrode layer includes a first region and a second region. The first region is contacted with an end surface of the element body and located near a joint boundary with the element body. The second region is located outside the first region and constituting an outer surface of the baked electrode layer. The first region includes a first glass having a predetermined composition. The second region includes a second glass having a predetermined composition.

  • Patent number: 9305708
    Abstract: A multilayer ceramic electronic device comprising a lamination in which an internal electrode layer 3 and a dielectric layer 2 are laminated alternatively, wherein the dielectric layer 2 is comprised of a dielectric ceramic composition including a main component represented by a general formula of ABO3 and a rare-earth component R, and segregation phases 5 including the rare-earth component R are present in the dielectric layer 2. When the dielectric layer 2 is separated to six areas by dividing the dielectric layer 2 sandwiched by a pair of the internal dielectric layers 3 in the thickness direction, there are the R segregation phases present in two neighboring areas 2a respectively adjacent to the pair of the internal electrode layers 3 in the dielectric layer 3 at a ratio of double or more compared with the R segregation phases present in two central areas 2b located at a substantially center in the dielectric layer 2.
