<p>PURPOSE:To provide a transformer placed close to a plurality of insulating conductors, which operates stably even in high frequency and which can be shielded with a simple magnetic sheet, by arranging a thin magnetic sheet and making part of the conductors a primary conductor and the rest a secondary conductor. CONSTITUTION:Two conductors C11 and C12 are placed in proximity to each other in parallel and the two are wound together in a planar manner. Conductors C11 and C12 are of approximately the same length and of approximately the same diameter, and part of the conductors are used as a primary conductor while the remaining part makes for a secondary conductor. A magnetic material Mm through coating or the like of magnetic powder is arranged on the surface of the conductors C to form a shield type air-core transformer. Also, a thin shield type air-core transformer is used for equipment such as a personal computer to enable personal equipment to be made in a thin form. Since this makes it possible for stable operation even in high frequency and shielding in a simple magnetic sheet, it can be placed directly near other parts. As a result, it can be placed with a high degree of freedom and equipment can be made small and thin.</p> |
