PROBLEM TO BE SOLVED: To enhance the transfer efficiency of a coaxial non-contact transformer using an electromagnetic induction system. SOLUTION: Formed materials consisting of a coil 2a formed by winding a wire material and two magnetic material cores, which pinch-in the coil 2a between them from the upper and lower sides and are formed into an annular discoid form, are used for a coaixal non-contact transformer, and these formed materials having different diameters are combined to each other into a concentrical form and in close proximity to the diametrical direction of the transformer, whereby the transfer efficiency of the transfomer is increased. Moreover, it is preferable that magnetic material sleeves 5a and 5b formed by winding a strip plate-shaped magnetic steel plate are provided on at least either of the inner peripheral part, which is formed on the innermost side of the core, and the outer peripheral part, which is formed on the outermost side of the core. |
