ABSTRACT:
A high-voltage transformer is provided which includes a primary coil and a secondary coil disposed in a coil case, and a support member attached to the coil case and having a high-voltage terminal for electrically connecting a lead wire of the secondary coil with an external electrical device. The primary and secondary coil are first accommodated in the coil case, and the lead wire of the secondary coil is temporarily connected with the high-voltage terminal while the support member is separated from the coil case and freely moved to an appropriate location. Then, the lead wire of the secondary coil thus temporarily connected is soldered to the high-voltage terminal. Thereafter, the support member having the high-voltage terminal thus soldered to the secondary coil lead wire is attached to the coil case. Finally, a resin is filled into the coil case so as to firmly secure the primary and secondary coils and the support member to the coil case.
