Abstract:
A method for manufacturing the spark plug comprising bending a ground electrode that is joined to a metal shell, along a first die, the first die having an end portion to be pressed against an inner surface of the ground electrode, and a flat surface portion contiguous to the end portion via a curved portion bulging outward, the flat surface portion being formed to be orthogonal to an axial line and includes a first step of pressing the end portion of the first die against the ground electrode.

Claim (Index 1):
A method for manufacturing a spark plug including: a tubular metal shell extending in a direction of an axial line from a front side toward a rear side; an insulator disposed in a tube hole of the metal shell and holding a center electrode at the front side; and a rod-like ground electrode having a first end portion joined to a front end portion of the metal shell, and having a second end portion bent to an axial line side so as to be opposed to the center electrode, the method comprising:\n a preparation step of preparing the metal shell having the ground electrode joined thereto; and a bending step of bending the ground electrode joined to the metal shell, along a first die to the axial line side, wherein the first die has an end portion to be pressed against an inner surface of the ground electrode, and a flat surface portion contiguous to the end portion via a curved portion bulging outward, the flat surface portion is formed so as to be orthogonal to the axial line or so as to be tilted to a first end portion side, toward the inner surface of the ground electrode, and the bending step includes a first step of pressing the end portion of the first die against the ground electrode.
