    摘要: To provide a technology of improving the corrosion resistance of a spark plug.
    A spark plug 100 includes a metal shell 1 on the outer surface of which a nickel plated layer is formed as a protective surface film. The nickel plated layer is such that when the atomic concentrations of constituent elements are measured in a depth direction by an X-ray photoelectron spectroscopy (XPS), the concentration of carbon atoms is 1.0% or more and 10.0% or less at a depth at which the atomic concentration of Ni elements is 80%.
