A board terminal is formed by cutting a metal wire material at a predetermined length, the metal wire material having a cross-sectional shape similar to and slightly larger than a terminal holding hole. A press-fit portion press-fitted to the terminal holding hole is pressure-forged in a direction orthogonal to an axis. Thereby, a tapered portion and a stepped edge portions are provided on both sides of the pressure-forging direction, the tapered portion tapering toward a press-fit direction, the stepped edge portion being provided to an end side of the tapered portion. Further, externally projected portions are provided to both sides of the press-fit portion in the direction orthogonal to the axis which is orthogonal to the pressure-forging direction.
