The invention provides an adaptor for inspection of circuit boards, by which an inspection operation can be smoothly carried out even when electrical inspection is continuously conducted on a great number of circuit boards to be inspected, the original service life of an anisotropically conductive elastomer sheet can be attained, and the anisotropically conductive elastomer sheet can be easily replaced by a new one when the anisotropically conductive elastomer sheet suffers from trouble, and an inspection apparatus for circuit boards, which is equipped with this adaptor. The adaptor for inspection of circuit boards of the invention is equipped with a wiring board for connection, on the front surface of which a plurality of connecting electrodes have been formed correspondingly to electrodes to be inspected, and an anisotropically conductive elastomer sheet detachably arranged on the front surface of the wiring board for connection. The anisotropically conductive elastomer sheet has a surface roughness of 0.5 to 5 µm on its front surface coming into contact with the circuit board, and a surface roughness of at most 0.3 µm on its back surface coming into contact with the wiring board for connection, the wiring board for connection has, on its front surface, an insulating layer formed in such a manner that each of the connecting electrodes is exposed, and the insulating layer has a surface roughness of at most 0.2 µm on its front surface. |
