<p><P>PROBLEM TO BE SOLVED: To make a planar transformer compact by inserting the spacer portion of a heat plate between a primary coil substrate and a secondary coil substrate, thereby effectively dissipating heat of primary and secondary coils. <P>SOLUTION: The planar transformer comprises a primary coil substrate 10 having a primary coil 11 and a secondary coil substrate 20 having a secondary coil 21, a heat plate 30 integrally having at least an insulating surface and a spacer portion 31 inserted into a gap between the primary coil substrate 10 and secondary coil substrate 20 which oppose with the gap, and an E-type ferrite core 40 provided in the primary coil substrate 10 and the secondary coil substrate 20. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
