Abstract: PROBLEM TO BE SOLVED: To provide a high voltage transformer wherein a distance between primary winding and secondary winding can be easily adjusted without changing bobbin. SOLUTION: A portion of secondary winding 4 wound in bank winding, which faces a rib 2A in an axial direction of a cylindrical part 2B, has a collar-side bank part 4A having such a collar-side bank angle 4b that the more distant from an upper surface 25A of the cylindrical part 2B the collar-side bank part 4A becomes, the more distant from the rib 2A the collar-side bank part 4A becomes in the axial direction of the cylindrical part 2B. That is, a virtual tangent 4a connecting a peripheral surface upper part of secondary winding 4-1, a peripheral surface upper part of secondary winding 4-5, a peripheral surface upper part of secondary winding 4-12, a peripheral surface upper part of secondary winding 4-22, and a peripheral surface upper part of secondary winding 4-35 forms the collar-side bank angle 4b, and the collar-side bank angle 4b is 20° in a direction going from the secondary winding 4-1 to the secondary winding 4-35 on the basis of an x-axis positive direction being the axial direction of the cylindrical part 2B and a direction of separating from the ring 2A.
