PROBLEM TO BE SOLVED: To decide an operating margin using a low frequency inspection clock signal. SOLUTION: An integrated circuit 100A contains a clock signal generation section 10 for generating an internal clock signal CKm, a processing section 20 for processing using the internal clock signal CKm, and an inspecting section 30A for inspecting the operating margin. The inspecting section 30A contains a combination circuit 32 having a plurality of logic circuits connected in series, a D flip-flop 31 for latching input inspection data Dtin with an inspection clock signal Ckt, and a D flip-flop 33 for latching an output signal 32a from the combination circuit 32 with the inspection clock signal Ckt to generate an output inspection data Dtout.
