  • Patent number: 11830675
    Abstract: A multilayer ceramic capacitor includes a multilayer body, a first outer electrode on a first main surface closer to a first end surface, a second outer electrode on the first main surface closer to a second end surface, a third outer electrode on the first main surface between the first outer electrode and the second outer electrode, a first inner electrode layer connected to the first outer electrode and the second outer electrode via a first lead electrode and a second lead electrode, and a second inner electrode layer connected to the third outer electrode via a third lead electrode. When a length of the first lead electrode and a length of the second lead electrode in the length direction are each denoted by a, and a length of the third lead electrode in the length direction is denoted by b, b/a is about 0.5 to about 0.83.

  • Patent number: 11721482
    Abstract: A method of producing a ceramic electronic component includes baking a first electrode paste containing a metal powder at a first temperature to form a first electrode layer at a first region of a ceramic body, baking a second electrode paste containing a metal powder of the same type as the metal powder in the first electrode paste at a second temperature lower than the first temperature to form a second electrode layer at a second region different from the first region of the ceramic body, and applying a physical shock treatment to a surface of the second electrode layer to densify a surface layer portion of the second electrode layer.

  • Publication number: 20230197338
    Abstract: A multilayer ceramic capacitor includes a multilayer body and three or more external electrodes. A first internal electrode layer includes a first counter electrode portion, a first extension portion, and a second extension portion. The first counter electrode portion includes a first central region, a first connection region connected to the first extension portion, and a second connection region connected to the second extension portion. Coverages of the first and second connection regions with respect to the dielectric layers are higher than a coverage of the first central region with respect to the dielectric layers, and coverages of the first and second extension portions with respect to the dielectric layers are higher than the coverage of the first central region with respect to the dielectric layers.

  • Patent number: 11065903
    Abstract: A gravure printing plate includes a cylindrical or substantially cylindrical gravure roller with a peripheral surface. Plural cells corresponding to a pattern to be printed are disposed on the peripheral surface of the gravure roller. First and second regions are provided on the peripheral surface of the gravure roller. The pattern to be printed includes at least two patterns. Plural cells corresponding to one of the two patterns are disposed in the first region. Plural cells corresponding to the other one of the two patterns are disposed in the second region.
