A conductive rod includes an outer tube unit, at least one insulating member, and a conductive unit. The outer tube unit is made of conductive material, and has a first end and a second end, the first end and the second end are communicated with a tube space. The insulating member is disposed on the first end of the outer tube unit. One end of the conductive unit is positioned on the insulating member, and the other end of the conductive unit extends toward the second end along the tube space of the outer tube unit. The conductive unit is not in contact with the outer tube unit. The present invention also provides a lamp, comprising at least one conductive rod as described above, a lamp holder combined with a top end of the conductive rod, and a base combined with a bottom end of the conductive rod.

A conductor shaping apparatus includes a driving device that relatively rotates an upper die and a lower die and integrally rotates the upper and lower dies with respect to a shaping member. The driving device rotates one of the upper and lower dies in a direction from an edgewise bent portion to a distal end of a conductor so as to separate the one of the upper and lower dies from the other. One of the upper and lower dies includes a supporting surface configured to support a side surface of an end portion of the conductor as the edgewise bent portion is formed in the end portion, and a guide surface that is formed to intersect the support surface. The guide surface extends away from the end portion of the conductor in a direction opposite to a bent direction of a flatwise bent portion closest to the edgewise bent portion as it extends away from the supporting surface on an opposite side of a rotational axis.
