  • Patent number: 10770205
    Abstract: A method for manufacturing an electronic component including a step of providing an outer electrode that includes a step of providing a sintered layer containing a sintered metal, a step of providing an insulation layer containing an electric insulation material, and a step of providing a Sn-containing layer containing Sn. The sintered layer extends from each of end surfaces of an element assembly onto at least one main surface thereof. The insulation layer is directly provided on the sintered layer at each of the end surfaces so as to extend in a direction perpendicular or substantially perpendicular to a side surface of the element assembly, and defines a portion of a surface of the outer electrode. The Sn-containing layer covers the sintered layer except for a portion of the sintered layer that is covered by the insulation layer, and constitutes another portion of the surface of the outer electrode.

  • Patent number: 10734142
    Abstract: In a method for manufacturing an electronic component, a step of providing an outer electrode includes a step of providing a sintered layer including a sintered metal, a step of providing a reinforcement layer not containing Sn but including Cu or Ni, a step of providing an insulation layer, and a step of providing a Sn-containing layer. The sintered layer extends from each end surface of an element assembly onto at least one main surface thereof to cover Bich. The reinforcement layer covers the sintered layer entirely. The insulation layer is directly provided on the reinforcement layer at each end surface of the element assembly and defines a portion of a surface of the outer electrode. The Sn-containing layer covers the reinforcement layer except for a portion of the reinforcement layer that is covered by the insulation layer, and defines another portion of the surface of the outer electrode.

  • Publication number: 20180040397
    Abstract: In an electronic component, an outer electrode includes a sintered layer including a sintered metal, a reinforcement layer not containing Sn but including Cu or Ni, an insulation layer, and a Sn-containing layer. The sintered layer extends from each end surface of an element assembly onto at least one main surface thereof to cover each end surface of the element assembly. The reinforcement layer extends on the sintered layer and covers the sintered layer entirely. The insulation layer is directly provided on the reinforcement layer at each end surface of the element assembly, extends in a direction perpendicular or substantially perpendicular to a side surface of the element assembly, and defines a portion of a surface of the outer electrode. The Sn-containing layer covers the reinforcement layer except for a portion of the reinforcement layer that is covered by the insulation layer, and defines another portion of the surface of the outer electrode.
