Abstract: A contact terminal includes a tubular body extending in an axial direction parallel to a central axis of the contact terminal and a bar-shaped conductor having conductivity. The conductor includes a protrusion protruding toward one side in the axial direction from the tubular body, and an insertion portion disposed inside from an outer periphery of the tubular body. The tubular body includes an end side notch provided along the axial direction on a peripheral surface of the one end portion in the axial direction of the tubular body, and a first circumferential notch connected to another side in the axial direction of the end side notch and provided along a circumferential direction away from the end side notch with respect to a first end portion in a circumferential direction of the end side notch.

Abstract: A contact terminal may include an outer tubular body being tubular and conductive and an inner tubular body being tubular and conductive, that is inserted into a cylinder of the outer tubular body. An outer first spring part that is elastic in an axial direction of the outer tubular body and whose winding direction is a first direction to be formed into a helical shape, may be formed on the outer tubular body. An inner first spring part that is elastic in an axial direction of the inner tubular body and whose winding direction is a second direction that is opposite to the first direction to be formed into a helical shape, may be formed on the inner tubular body.

Abstract: An inspection jig may include: an electrode; a probe, the probe having a rear end portion and a tip portion to contact a bump; and a support member supporting the probe. The probe may include: an outer tubular body that is electrically conductive; and an inner tubular body that is electrically conductive, the inner tubular body being inserted into the outer tubular body. The outer tubular body may include outer spring parts to bias the rear end portion. The inner tubular body may include inner spring parts. The tip portion may be a first end of the inner tubular body, and protrudes from a first end of the outer tubular body. The support member may hold the outer tubular body such that the rear end portion is brought into contact with the electrode by the biasing force of the outer spring parts.

Abstract: A contact terminal may include a tubular body made of an electrically conductive material; and stick-shaped first and second central conductors made of an electrically conductive material. The first and second central conductors may include first and second stick-shaped bodies, first and second clasped portions configured to have a diameter greater than that of each of the first and second stick-shaped bodies, and first and second swell portions configured to have a diameter greater than that of each of the first and second stick-shaped bodies. The first and second central conductors are arranged to have a distal end portion of the first and second swell portions inserted into a joining portion of the tubular body, and to have a distal end surface of the first swell portion and a distal end surface of the second swell portion opposite each other with a gap therebetween.
