  • Patent number: 12198858
    Abstract: A multilayer electronic component includes: a body and an external electrode disposed on the body, wherein the external electrode includes a conductive resin layer containing a bisphenol A-based resin and a biphenyl-based resin with a specific mixing ratio (e.g., a ratio of a content of the biphenyl-based resin with respect to a total content is 10 wt % or more and 50 wt % or less). Such a resin mixing ratio between the bisphenol A-based resin and the biphenyl-based resin can lead to 0.337?2*C/A?0.367 or 0.048?B/A?0.14, with an aromatic ring peak intensity (A), a carbonyl peak intensity (B), and an alcohol peak intensity (C) in a Fourier transform infrared spectroscopy (FT-IR) analysis. The multilayer electronic component showing such peak intensity characteristics can suppress oxidation of a conductive resin layer while also securing excellent adhesive strength of the conductive resin layer.
