<p>PROBLEM TO BE SOLVED: To provide a small low-cost high-voltage generating coil for reducing the decrease in secondary voltage and noises to a minimum. SOLUTION: A high-voltage generating coil includes a primary coil and a secondary coil wound around a bobbin 32b made of synthetic resin. The bobbin 32b has a plurality of shunt winding brims 32ba, by which secondary coil winding grooves 32d are separated around its outer circumferential part. Each primary coil winding groove 32c is provided around a given number of shunt winding brims 32ba, and the secondary coils 32f are wound around the secondary coil winding groves 32d. In addition, U-shaped primary coil pieces 32e are inserted in the primary coil turning grooves 32c and the primary coil members 32e are connected in a coil state.</p> |
