PROBLEM TO BE SOLVED: To provide an electrical contactor having a stable resistance value even if being used repeatedly.SOLUTION: An electrical contactor includes: a plunger having a contact part coming into contact with an inspection object; a support part used for positioning; and a spring coil for connecting the plunger to the support part. The spring coil has, at a side to be connected to the support part, a densely wound portion of a double spiral structure consisting of two different wire rods. A brake shaft part provided to the plunger extends inside the spring coil from the plunger to the densely wound portion, and the outer peripheral surface of the tip portion of the brake shaft part comes into contact with the surface of one of two wire rods in the inside face of the densely wound portion. |
