<P>PROBLEM TO BE SOLVED: To provide a step-up transformer that stabilizes output voltage by reducing stray capacitance. <P>SOLUTION: A secondary winding 4 is wound on a core portion 21 in a plurality of layers and a start wire S2 as a start of winding of the secondary winding 4 on the core portion 21 is covered by the upper layer of the secondary winding 4, and a primary winding 3 is wound outside the upper layer of the secondary winding 4. The upper layer of the secondary winding 4 can be interposed between the start wire S2 and the start of winding S1 of the primary winding 3 to prevent contact between the start wire S2 and the start of winding S1 of the primary winding 3. The step-up transformer 1A can thus reduce stray capacitance between the start wire S2 and the start of winding S1 of the primary winding 3 to stabilize output voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
