Claims

[Scope of utility model registration request]

A low-voltage coil bobbin around which a primary coil is wound and a catch is provided at one end of a core insertion hole, a high-voltage coil bobbin located on the outer peripheral side of the low-voltage coil bobbin and around which a secondary coil is wound, and a high-voltage coil bobbin around which a secondary coil is wound. In the flyback transformer, the flyback transformer includes an insulating case that covers the outer peripheral side of the coil bobbin, and a core that is disposed between the core insertion hole of the low-voltage coil bobbin and the outside of the insulating case, and a portion of which is seated on the seat of the low-voltage coil bobbin. A flyback transformer characterized in that the catch seat is provided with a protrusion that projects in the axial direction, and the core is provided with a positioning hole that is press-fitted onto the protrusion to position the core.
