The invention provides a power transmission coil structure. A power transmission coil structure (1) is provided with: a flat first magnetic body (10); a second magnetic body (20) including a central magnetic body (21) provided in the central portion of the surface of the first magnetic body (10) and an outer peripheral magnetic body (22) provided in the outer peripheral portion of the surface of the first magnetic body (10); a third magnetic body (30) provided between the central magnetic body (21) and the outer peripheral magnetic body (22); and a coil (40) disposed on the surface of the third magnetic body (30) and wound around the center magnetic body (21). The second magnetic body (20) has a relative permeability that is three times or more higher than that of the third magnetic body (30).
本发明提供一种电力传输线圈结构。电力传输线圈结构(1)包括:平板状的第一磁性体(10);第二磁性体(20),包括设置在第一磁性体(10)表面的中央部的中央磁性体(21)、以及设置在第一磁性体(10)表面的外周部的外周磁性体(22);第三磁性体(30),设置在中央磁性体(21)与外周磁性体(22)之间;以及线圈(40),配设在第三磁性体(30)的表面部,缠绕在中央磁性体(21)的周围。第二磁性体(20)具有比第三磁性体(30)高三倍以上的相对磁导率。
