Abstract

PURPOSE:To eliminate a secondary winding and a bobbin, and provide very small equipment by forming a secondary coil with a spiral or square swirling conductive wire-like piece on an insulating sheet material. CONSTITUTION:A high-frequency transmission transformer 4 is formed by winding a primary coil 6 around a ferrite core 5. 7 shows a cylindrical battery which is separated when required from the high-frequency transmission transformer and arranged so as to face the high-frequency transmission transformer. A secondary coil 8 which is set up on the battery is formed with spiral or square swirling conductive wire-like pieces 12, 12' in insulating sheet 11, 11'. Insulating sheet materials 11, 11' are formed with for example, polyimide base. The conductive wire-like pieces 12, 12' are formed by coating with a conductive film such as copper on the sheet material 11, 11' and etching this conductive film, or bonding foil material on the sheet material 11, 11'.
