发明名称 MAGNETIC SHEET, TRANSMISSION COIL COMPONENT, AND NON-CONTACT CHARGING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a magnetic sheet capable of contributing to miniaturization/simplification and improvement in characteristics, such as efficiency, of a non-contact charging device and a transmission coil component or the like used therefor, and to achieve miniaturization or the like of a transmission coil component and a non-contact charging device by using the magnetic sheet.SOLUTION: The magnetic sheet for a non-contact charging device has, on the side of one main surface thereof, a first recess which is substantially annular when viewed from a normal direction of the main surface. A distance between the bottom surface of the first recess and the other main surface is smaller than the depth of the first recess.
