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.

A withstand voltage-testing apparatus includes a high voltage generator for applying a high voltage to a work, the withstand voltage of which is to be measured. A ground conductor covers the work with an insulating material. A conductor is wound around a current transformer to connect the ground conductor and the ground. A variable resistor is connected with the output terminals of the current transformer. A digital panel meter, which includes a detector, detects a voltage generated by the variable resistor. A warning mechanism displays that work produced by the above is defective when a voltage detected by the detector is higher than a predetermined value.
