る電流センサのコアの構造。[Claims for Utility Model Registration] An annular magnetic core with a gap formed by a cutout, a coil wound around an insulating bobbin fitted on one side of the core, and a substrate with a magnetoelectric transducer mounted on its surface. In the current sensor, the substrate is arranged such that the magnetoelectric transducer is located in the notch of the core, wherein the annular magnetic core has one side other than the short side having the gap in length. 2 divided along the direction
What is claimed is: 1. A current sensor core structure comprising two divided cores, wherein connecting sides of the two divided cores are inserted into a hollow part of the bobbin and connected to each other.
