An internal connection output pad (14A) connected to a CMOS output circuit (15A, 16A) on a first chip (11A) is electrically connected via a chip-to-chip bonding wire (17) to an internal connection input pad (14B) connected to a CMOS input circuit (15B, 16B) on a second chip (11B). In order to inspect the presence or absence of leakage resistance (40), a test circuit (30) controls a high-impedance output state, a high-level output state and a low-level output state of the internal connection output pad (14A) via the CMOS output circuit (15A, 16A). If a difference between a value obtained by measuring a current flowing through a power supply to a ground in the high-impedance output state and a value obtained by measuring such a current in the high-level output state is calculated, a transistor leakage current is canceled, so that a correct minute leakage current can be detected.
