PROBLEM TO BE SOLVED: To precisely measure the frequency characteristics of a circuit to be measured inside a chip, even when the output current capacity of the circuit to be measured is small. SOLUTION: This device is configured to arrange an output buffer 5 and a pad 6 within a scribe lane 2, connect an input part 15 of the output buffer 5 to the output of the circuit 3 to be measured via a first fuse 4, connect a first power source 8 of the output buffer 5 to a first power source 7 of the chip 1 via a second fuse 9, and connect a second power source 11 of the output buffer 5 to a second power source 10 of the chip 1. According to this configuration, the frequency characteristics of the circuit 3 to be measured can be improved by the output buffer 5, and this device further comprises a circuit 12 for cutting the first fuse 4 and the second fuse 9, after the inspection of frequency characteristics arranged within the scribe lane 2.
