PROBLEM TO BE SOLVED: To measure a parameter without being affected by a skew. SOLUTION: This measuring instrument is constituted at least of a signal measuring means 30 for outputting an input clock signal CK0 and an input data signal DATA0 for measurement, and a skew absorbing means 40 for absorbing the skews in the input clock signal and the input data signal. A clock signal CKin for measurement and a data signal DATAin for measurement of which the skews are absorbed are supplied to an integrated circuit 10, and the parameter (for example, a set-up time and a holding time) of the integrated circuit in signal writing are measured based on an output signal DATAout for determination output from the integrated circuit. The parameter is measured highly precisely since the skews are measured based on the clock signal CKin for the measurement and the data signal DATAin for the measurement of which the skews are absorbed.
