<p>PROBLEM TO BE SOLVED: To measure the measuring current flowing in a circuit without having any influence on the circuit system where the measuring current flows. SOLUTION: This current measuring device comprises a magnetic resistance element arranged in the vicinity of a signal line so that the magnetic field generated in the flowing of the measuring current to the signal line acts thereon, and a means for measuring the measuring current according to the change of the resistance of the magnetic resistance element according to the intensity of the working magnetic field.</p> |
