Abstract
A current detection element includes a laminate where multiple insulator layers are laminated, a main line conductor formed in the laminate, extending in one direction, a coil-shaped current detection conductor that is formed in the laminate and that is magnetically coupled with the main line conductor, and electrostatic shielding conductors that are formed in the laminate, and that are grounded. The electrostatic shielding conductors overlap at least one of the main line conductor and the current detection conductor in plan view from a winding axis direction along a winding axis of the current detection conductor. Accordingly, a current detection element that accurately detects high-frequency AC current flowing through a line, and a transmission device and electric power transmission system having the same, are provided.
