Abstract:
A probe member for wafer inspection having a sheet-like probe, the probe including a frame plate in which openings are formed, and contact films arranged on a front surface of the frame plate so as to close the openings, each of the contact films obtained by arranging, in an insulating film formed of a flexible resin, a plurality of electrode structures, and an anisotropically conductive connector, which is composed of a frame plate, in which a plurality of openings have been formed corresponding to the electrode regions, and a plurality of elastic anisotropically conductive films arranged on and supported by the frame plate so as to close the respective openings, wherein each of the openings of the frame plate in the sheet-like probe have a size for receiving the external shape in a plane direction in the elastic anisotropically conductive film of the anisotropically conductive connector.
