<p><P>PROBLEM TO BE SOLVED: To provide a bobbin for a transformer having structure securing a withstand voltage property while thinning a tubular base part, and preventing a short circuit between the high-voltage side of a winding and a core; and a high-voltage transformer. <P>SOLUTION: Whereas in-hole projecting parts 19A-19D for supporting an inserted core are formed on the inner peripheral surface 16 of a through-hole 11, the in-hole projecting parts 19A-19D are not formed in a projecting part non-formation region 17 set on one end side of the through-hole 11, and a predetermined air gap is secured throughout the total circumference between the outer peripheral surface of the inserted core and the inner peripheral surface 16 of the through-hole 11. A high-voltage-side part of a secondary winding is wound around a part located on a radially outer side of the through-hole 11 with respect to the projecting part non-formation region 17 of the tubular base part 10, and an insulation coating treatment is applied to a part of the core located in the projecting part non-formation region 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
