Abstract
A probe pin includes an elastic hollow cylinder that expands and contracts along a central axis, a conductive first plunger extending in the cylinder along the central axis from a first end of the cylinder, and a conductive second plunger extending in the cylinder along the central axis from a second end of the cylinder. The first and second plungers are coupled together in the cylinder in a manner movable relative to each other along the central axis. The first plunger includes a first plunger body contained in the cylinder, and a first terminal connected to the first plunger body and located outside the cylinder. The second plunger includes a second plunger body contained in the cylinder, and a second terminal connected to the second plunger body and located outside the cylinder. The first plunger body includes a slope that tapers in a direction from an outer side toward an inner side of the cylinder, comes in contact with the second plunger body inside the cylinder, and is urged in a direction crossing the central axis by relative movement of the first and second plungers. The first plunger body includes a deformable elastic portion between the first terminal and the slope.
