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 includes a tubular body and a first conductor. The tubular body has an end-side cutout provided in a shape cut out from one axial-direction end surface toward an other axial-direction side at one axial-direction end portion of the tubular body, a hole that is open at the one axial-direction end portion, and a pair of arms interposed between the end-side cutout and the hole. The first conductor includes a first insertion including an inclined portion having an outside diameter gradually increased toward one axial-direction side, and a first straight portion connected to the one axial-direction side of the inclined portion and having an outside diameter constant along the axial direction. The outside diameter of the first straight portion is larger than an inside diameter of the tubular body. The first straight portion is configured to be in contact with the pair of arms.

Abstract: A contact terminal includes a tubular body extending in an axial direction of the contact terminal and having conductivity; a bar-shaped first conductor having conductivity and capable of coming into contact with an inspection target; and a bar-shaped second conductor having conductivity. The first conductor includes: a first protrusion that protrudes from the tubular body toward one side in the axial direction; and a first insertion portion provided at the other end of the first conductor in the axial direction and disposed in the tubular body. The second conductor includes a second insertion portion disposed in the tubular body. The tubular body includes: a spring portion configured in a spiral shape along a peripheral surface of the tubular body; and a first body portion connected to one side in the axial direction of the spring portion. The first insertion portion is fixed to the first body portion.
