<p>A substrate (50) is used for inspecting an electronic device (40) having bump-shaped connection terminals (42), and is used for an electrical test on the electronic device (40). The substrate includes opening sections (11), the diameter of which are determined so that a connection terminal (42) can be inserted into and drawn out from the opening (11), which are formed in a region on one side of an insulating substrate (10). The substrate (10) has an arrangement of connection terminals (20); and wiring patterns (14, 16) which corresponds to those of the electronic device (40). Each of the wiring patterns is composed of a pad section (16) exposed on a bottom face of the opening (11) so that the pad (16) can come into contact with the connection terminal (42) to accomplish electrical continuity, a connecting pad section (20) which is formed in a region outside of the region in which the pad section (16) is formed, and which comes into contact with a contact terminal (35) of an inspection device so as to accomplish electrical continuity, and a wiring section (14) for electrically connecting the pad section (16) with the connecting pad section (20). The wiring patterns (14, 16, 20) are formed on the other side of the insulating substrate (10). <IMAGE></p> |
