PROBLEM TO BE SOLVED: To find out a fuse element which is cut halfway. SOLUTION: A control signal CNT is turned into a high level and an NMOS transistor Q0 is turned on. Since a resistance value of a resistor R0 is a predetermined value at manufacturing a semiconductor integrated circuit device beforehand, a current I0 flowing through a measuring terminal P0 is measured by an external tester or the like, thereby determining a resistance value of a fuse element F0. If the resistance value (r) of the fuse element F0 is a certain value r1 or larger, for example, it is determined that the fuse element F0 is cut. If the resistance value (r) is a certain value r2 or smaller, it is determined that the fuse element is not cut. In the case of r2<r<r1, it is determined that the fuse element is cut incompletely.
