PROBLEM TO BE SOLVED: To measure delay time while stabilizing operation of a circuit.SOLUTION: A delay time measurement device (1) comprises: a first flip flop (31a) connected to an input side of a combinational circuit (21); a delay part (32) connected to an output side of a combinational circuit (31) and delaying an output signal, and capable of controlling a delay amount of a signal on the delay part (32); a second flip flop (31b) connected to an output side of the delay part (32); and measurement means (5C) for measuring delay time of the combinational circuit (21) based on a delay amount when a signal outputted from the second flip flop (31b) becomes a value which is not a preset expectation value. |
