A tape carrier comprises contact test patterns (31, 32) used for performing a conduction test on a tape base (2). More specifically, in addition to test pads (3) connected to outer leads used for input/output signals, the contact test patterns (31, 32) are formed on the tape base to test whether socket contactors (11) are in contact with the test pads (3). A conduction test is performed using the contact test patterns. The tape is repeatedly reset to the socket until a conductive state is established, thereby preventing a test error. <IMAGE> |
