摘要： The present invention provides a spark plug which is capable of suppressing a occurrence of crack and separation by determining a structural configuration of a melting portion formed in a junction portion between a discharge portion and a pedestal portion which form an ignition portion that protrudes from a ground electrode. In a profile line shape of a cross section including a center axis P of an ignition portion 80, an exposure surface 88 of a melting portion 83 connects a side surface 82 of a discharge portion 81 and a side surface 85 of a pedestal portion 84. Further, an exterior angle θ formed between an imaginary line Q, which passes through a boundary position X1 between the melting portion 83 and the pedestal portion 84 and a boundary position X2 between the melting portion 83 and the discharge portion 81, and the center axis P at a node C, satisfies 135°≦θ≦175°. Furthermore, a proportion T/S of a forming depth T of the melting portion 83 to an outside diameter S of the discharge portion 81 satisfies T/S≧0.5.

摘要： The ignitability of a spark plug configured without a noble metal for a center electrode and a ground electrode is improved. The spark plug comprises a center electrode, an insulator, a metal shell, and a ground electrode including a discharge surface. The ground electrode forms a spark gap between the discharge surface and the center electrode. The center electrode and the ground electrode both do not include a noble metal. The ground electrode comprises a proximal end portion combined with the metal shell and positioned above, the discharge surface and a distal end portion including the discharge surface and positioned below the proximal end portion while continued from the proximal end portion. A width Da of the center electrode viewed from a first direction and a width Db of the proximal end portion viewed from the first direction satisfy Db/Da≦0.92. The first direction is perpendicular to the axial direction and directing from the proximal end portion to the center electrode.
