。[Claims for Utility Model Registration] A cylindrical mounting bracket is fitted around a rod-shaped center electrode via an insulator, and a rod-shaped outer electrode is attached to the tip of the metal fitting so that its tip is aligned with the axis of the center electrode. In a spark plug having a structure in which the central electrode is bent to face a center electrode, a hemispherical or similar-shaped depression is formed on the discharge surface of the center electrode, and a conical or similar depression is formed on the discharge surface of the outer electrode. It is constructed by providing a protrusion with a similar shape, or by forming the above-mentioned depression on the outer electrode and providing the above-mentioned protrusion on the center electrode. A spark plug characterized by giving a negative charge to a discharge part having a projection.
