A current measuring device is provided to enable accurate measurement of a high-frequency current even if a strong interference field exists. A current measuring device includes a coil unit(3), which comprises a coil conductor(4) and a circuit(5) connected to the coil conductor. At least a part of the coil unit is enclosed by a coil shield(11). The coil shield and the circuit are connected to a ground potential independently. The coil shield and the circuit include ground connectors(9,12), respectively. The ground connectors are apart from each other and connected to the ground potential. The coil shield and the circuit are connected to a common ground plate or different ground plates. |
