摘要： A spark plug having excellent load life performance even when the spark plug receives an impact or vibration. The spark plug includes an accommodated portion of a metallic terminal, which is accommodated in an axial hole of an insulator, having a plurality of bent portions formed as a result of proper bending of the accommodated portion. The bent portions are in close vicinity to an inner circumferential surface of the insulator at three or more locations, and are present without localizing in the radial direction of the axial hole.
