摘要： There is provided a high frequency current detecting apparatus which can measure a high frequency current with high precision without cutting a circuit conductor. The high frequency current detecting apparatus includes a core having a hollow portion, a first conductive material inserted in the hollow portion of the core and having both ends respectively protruding from both ends of the hollow portion to form probe portions, a second conductive material electrically insulated from the first conductive material and inserted in the hollow portion of the core, a resistor for generating a voltage corresponding to a high frequency current flowing through the second conductive material while the first conductive material is made a primary coil and the second conductive material is made a secondary coil, and a shield provided around the core.
