Abstract
A spark plug includes a metal shell, an insulator, a center electrode, a ground electrode, and a terminal fixed to the insulator. The dimensional parameters in the structure of the spark plug, such as a maximum diameter A of the terminal and a diameter B of the insulator satisfy a dimensional relationship defined through experimental investigation. The structure facilitates an attachment of a plug cap to the spark plug.
