Abstract:
A contact (44), comprising a first coiled spring (441), a second coiled spring (442) installed in the hollow part of the first coiled spring (441) and having a length shorter than the length of a wire material forming the first coiled spring (441), and contact parts (443) provided at both ends of the first coiled spring (441) and the second coiled spring (442), whereby, since the contact (44) does not have a probe part and a casing though a probe pin has the probe part and the casing, an inductance component can be decreased and a pitch can be reduced and, since the contact (44) does not use conductive resin material, the contact (44) has an excellent durability.
