<p>PROBLEM TO BE SOLVED: To make the assembling work of a high-voltage coil easier so as to improve the reliability of the coil by preventing an external force applied to the grounding conductor of the coil from being transmitted to the winding starting part of the coil. SOLUTION: A transformer is formed by housing a voltage transforming section provided with a low-voltage coil 2 wound around a closed magnetic circuit point and a high-voltage coil 3 wound around a bobbin 20 in multiple layers and coaxially positioned with the coil 2 in a container together with an insulating medium. The bobbin 20 of the high-voltage coil 3 is formed of a metallic or conductive cylindrical bobbin having an insulating section for preventing one-turn circuit and the winding starting end section 22 of the coil 3 and one end of a grounding conductor 23 are electrically connected to the bobbin 20. Then the other end of the grounding conductor 23 is lead out of the container and grounded.</p> |
