<p><P>PROBLEM TO BE SOLVED: To drastically reduce magnetic interference between neighboring elements for a composite wiring element made by integrating two or more elements. <P>SOLUTION: A composite transformer 10, made by integrating transformers T1 and T2, includes coil wirings 20 and 30 corresponding to the transformers T1 and T2, respectively, and includes: bobbins 12 on which primary wirings 22A and 32A and secondary wirings 22B and 32B are wound; an I magnetic body core 50 inserted through hollows of the bobbins 12; and an E magnetic body core 60 placed so as to face to the side face of the I magnetic body core 50. A gap G1 is formed between a magnetic-body core end 50A and a magnetic-body core end 60A, a gap G2 is formed between a magnetic-body core end 50B and a magnetic-body core end 60B, and a magnetic-body core center 60C and a magnetic-body core center 50C are brought into contact with each other. Providing the gaps G1 and G2 enables mutual magnetic interference between the neighboring transformers T1 and T2 to be reduced drastically. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
