description A park plug includes a tubular insulator extending along and centered on an axis, and a tubular metal shell secured to an outer peripheral surface of the insulator by crimping, in which powder for sealing is filled between the outer peripheral surface of the insulator and an inner peripheral surface of the metal shell. A relationship between a minimum outer diameter d of the insulator and a maximum inner diameter D of the metal shell in a filling-up area satisfies 1.12 ‰¤ D/d ‰¤ 1.16, the minimum outer diameter d being in the filling-up area where the powder is filled between the metal shell and the insulator.
