PURPOSE:To make lead wires unnecessary, make miniaturization possible, and obtain a transformer of high reliability, by making the intervals of pins arranged on a dual-in-line non-uniform in accordance with the insulation distance required for each winding. CONSTITUTION:The bobbin 21 of a high frequency transformer is provided with pins 1-20, and a winding 22 is wound around a core 23 via a bobbin 21. The pins 1-12 are used for a base driving +, - winding of each transistor of an inverter, and all arranged on a line of one side of a dual-in line. Independent terminal pins for a power source winding corresponding with each transistor are so arranged that the insulation distance is enlarged by expanding the pin interval (a). The other pin intervals are (b), which is smaller than (a). As the result, lead wires for terminals are made unnecessary.
