<p><P>PROBLEM TO BE SOLVED: To provide a magnetic device using a magnetic substance having a high magnetic flux density and advantageous heat releasing properties as a core of a transducer or a choke coil and applied with a countermeasure against the heat evolution of a winding. <P>SOLUTION: This magnetic device comprises: (i) a core structure constituted of a plurality of cores each containing a magnetic substance of an amorphous metal having a first magnetic path inserted into at least one coil and a second magnetic path connected in parallel to the first magnetic path; and (ii) a laminated structure constituted by laminating at least one substrate in which a conductive substance pattern is formed and at least one insulated sheet in which an aperture for inserting the first magnetic path is provided, wherein the conductive substance pattern constitutes the coil into which the first magnetic path is inserted and the width of the conductive substance pattern in a second direction perpendicular to a first direction in which the first and the second paths are aligned is larger than the distance between the first and the second magnetic paths. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
