摘要： The holder for an electroconductive contact unit according to the present invention uses a silicon wafer having a laminated structure including a first silicon layer, second silicon layer and silicon oxide film which is disposed between the two silicon layers. A small hole is formed in the first silicon layer for coaxially and slidably guiding a head portion of an electroconductive needle member, and a large hole is formed in the second silicon layer for receiving a flange portion of the needle member and a compression coil spring so that the silicon oxide film serves as a stopper for the flange member. Thus, by finishing the surface of the first silicon layer by lapping, the projecting length of the electroconductive needle member can be defined at a high precision. When the object to be tested consists of a silicon wafer, because the holder is made of the same material as the object to be tested, and they undergo a substantial identical thermal expansion, there is no positional shifting of each electroconductive needle member in simultaneously accessing a plurality of points.
