Abstract:
An ignition plug such as a spark plug or a glow plug configured to ignite an air-fuel mixture in an internal combustion engine includes a mark that is formed of an oxide film generated on the surface of a metal member or is formed of the metal member and the oxide film. The mark is formed by promoting formation of the oxide film on the surface of the metal member or removing the oxide film through radiation of a laser beam onto the surface of the metal member.
