Abstract: A multilayer ceramic electronic component includes a first organic layer that covers from a first base electrode layer to at least a portion of a surface of a laminated body, a second organic layer that covers from a second base electrode layer to at least a portion of the surface of the laminated body, a first plating layer that includes a leading end in contact with the first organic layer and that has an atomic concentration ratio of Si to Cu of about 1% or more and about 5% or less between a Cu concentration and an Si concentration at the surface of the first organic layer, and a second plating layer that includes a leading end in contact with the second organic layer and that has an atomic concentration ratio of Si to Cu being about 1% or more and about 5% or less between a Cu concentration and an Si concentration at the surface of the second organic layer.

Abstract: A multilayer ceramic electronic component includes a first plating layer in contact with a first organic layer and a second plating layer in contact with a second organic layer. When the first organic layer disposed on a first base electrode layer located on a first principal surface or a second principal surface, or the second organic layer disposed on a second base electrode layer located thereon, is referred to as an organic layer principal surface portion, and when the first organic layer disposed on the first base electrode layer located on a first end surface or a second end surface, or the second organic layer disposed on the second base electrode layer located thereon, is referred to as an organic layer end surface portion, the surface roughness of the organic layer end surface portion is larger than the surface roughness of the organic layer principal surface portion.

Abstract: An adsorbent that includes a particle of a layered material that contains one or a plurality of layers; and contains Li. The one or plural layers includes a layer body represented by: MmXn where, M represents at least one Group-3, -4, -5, -6, or -7 metal, X represents a carbon atom, a nitrogen atom, or a combination thereof, n is 1 to 4, and m is larger than n, and equal to or less than 5; and a modified/terminal part T resides on a surface of the layer body, T represents at least one selected from the group consisting of hydroxy group, fluorine atom, chlorine atom, oxygen atom, and hydrogen atom, the modified/terminal part T residing on a surface of the layer body, the particle has an average thickness of 1 nm to 10 nm, and the adsorbent has a Li content of 0.0001% by mass to 0.0020% by mass.
