摘要： A power supply transformer that can ensure a desired inter-coil creeping distance with no risk of insulation breakdown when high voltage is applied. The power supply transformer includes a case having a bottomed double tubular shape, a first coil accommodated between inner and outer tubes of the case, a lid body that closes an upper opening of the case, a second coil disposed on the upper surface of the lid body, and a core surrounding the case and the second coil. The first coil is formed only of a round wire wound in multiple layers. The lid body has a flat plate section on which the second coil is placed and a tubular inner wall section and outer wall section that cover the inner and outer circumferences of the second coil and stand on the flat plate section.
