PROBLEM TO BE SOLVED: To provide a current probe capable of injecting a common mode noise to a cable present in a small space, a short cable or the like. SOLUTION: This current probe is constituted so as to generate a common mode noise current 8 on a cable 7 when the cable 7 is arranged in the form of passing through a cylindrical small ferrite bead 2, a noise generating means is connected to BNC connector 6, and a noise signal is transmitted therefrom. Accordingly, the application of the common mode noise to the cable present in the small space, the short cable or the like which was impossible in a conventional current probe can be performed.
