PROBLEM TO BE SOLVED: To provide a low-cost and wiping-allowing probe pin. SOLUTION: The probe pin 100 includes a sleeve 110 made of a conductive metal, a spring 120 axially housed in the sleeve, a plunger 130 projectable from one end of the sleeve 110 and connected to one end of the spring 120, and a plunger 140 projectable from the other end of the sleeve 110 and connected to the other end of the spring 120. In the sleeve 110, a guide hole 112 is formed for regulating axial movement and rotation of the plunger 130 while a guide hole 114 is formed for regulating axial movement and rotation of the plunger 140. Further, projections 136 and 146 to be inserted into the guide holes 112 and 114 are formed on the plungers 130 and 140, respectively. COPYRIGHT: (C)2009,JPO&INPIT
