Patent ID: 7705618

Claim:
An adaptor device comprising: an adaptor body that includes a connecting electrode region, on a surface of which a plurality of connecting electrodes are formed in accordance with a pattern corresponding to electrodes to be inspected in a circuit device to be inspected; and an anisotropically conductive connector arranged on the connecting electrode region of the adaptor body, wherein the anisotropically conductive connector includes a composite conductive sheet that includes an insulating sheet, in which a plurality of through-holes each extending in a thickness-wise direction of the sheet are formed, and rigid conductors arranged respectively in the through-holes in the insulating sheet so as to protrude from both surfaces of the insulating sheet, wherein each of the rigid conductors has terminal portions formed on both ends of a body portion inserted into the through-hole in the insulating sheet and each includes a diameter greater than a diameter of the through-hole in the insulating sheet, and is movable in the thickness-wise direction of the insulating sheet, and the rigid conductors are arranged in accordance with a pattern that corresponds to the connecting electrodes in the adaptor body, and a first anisotropically conductive elastomer sheet arranged on one surface of the composite conductive sheet and a second anisotropically conductive elastomer sheet arranged on the other surface of the composite conductive sheet.
