    摘要: A plunger includes a conductive base layer, and a platinum group layer which is provided on the outside of the base layer and which contains a platinum group element as a main component. The plunger has the base layer as its base material, and has the platinum group layer on the outside of the base layer at the tip part to come into contact with an inspection object. A contact probe includes the plunger, and a spring which abuts on the plunger at an end part.

    摘要: A socket includes: a contact probe; and an insulating support body supporting the contact probe. The contact probe includes: a first plunger to be connected with an object to be inspected; a second plunger to be connected with an inspecting board; and a spring configured to urge the first plunger and the second plunger in a direction apart from each other. In a state where a tip end of the first plunger is released, a projecting amount of the second plunger from the insulating support body is zero with a natural length of the spring.

    摘要: A spring connector includes a plunger; a contact member; and a spring for urging the plunger and the contact member so as to separate the plunger and the contact member from each other. The spring is an insulation coated metallic wire which is molded into a coil-like shape. Metal is exposed from both end faces of the insulation coated metallic wire, and at least one end part of the spring is bent inward.
