Zusammenfassung:	There is provided a current transformer that a connecting mechanism by which cores can be opened or closed, a water-proof property can be achieved by a simple structure. A pair of divided cores (11, 12), which are openably and closably connected to each other by means of a hinge member (15), are closed in a ring-shape by inserting ends of the divided cores into connecting members (17) having a tube shape, and sealing bodies (18) provides a sealing performance between the connecting members (17) and the outer cover body (14) at the ends of the divided cores. It is therefore possible to ensure easily a water-proof state by bringing the sealing body (18) into contact with the connection members (17) and the outer cover body (14), and simplify the respective structures for providing a water-proof performance, thus making it possible to reduce a size and weight of the current transformer.
