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 load port adapter is a load port adapter fixable on a mounting table of a load port. The load port adapter includes a holder capable of holding a cassette capable of accommodating a plurality of circuit boards. The holder is fixable on the mounting table of the load port. The holder includes a position adjustment mechanism configured to position the cassette at a reference position. In the cassette clamped on the load port adapter, the reference position is a reference position on a load port adapter side when the circuit board is taken out from the cassette.

Abstract: An inspection jig includes contact terminals and a pitch conversion unit electrically connected to the contact terminals and configured to convert a first pitch between adjacent two of the contact terminals into a second pitch different from the first pitch. The contact terminals each include a tubular body that extends in an axial direction of the contact terminal and is electrically conductive, and a conductor that is electrically conductive and has a stick shape. The tubular body includes a spring portion that has a helical shape along a peripheral surface of the tubular body. The conductor includes an uninserted portion that protrudes from the tubular body toward a first side in the axial direction, and an inserted portion that is disposed in the tubular body and is fixed to a first axial end portion of the tubular body. The pitch conversion unit includes a board portion and a protruding portion.
