PROBLEM TO BE SOLVED: To provide a high-voltage power supply wherein a high-voltage circuit can be favorably molded without incurring an increase in the number of parts or the complication of working processes. SOLUTION: The area on a single circuit board 20 is divided into a low-voltage area 20a positioned on one end side and a high-voltage area 20b positioned on the other end side, and a low-voltage circuit portion 5 and a high-voltage circuit 6 are constructed in the respective areas. An insulated case 30 has one end opened as a board insertion hole 30a. The circuit board 20 is inserted into this case from the other end side to cover the high-voltage circuit portion 6. Then, insulating filler 35 is filled only on the high-voltage circuit portion 6 side on the circuit board 20, and it is molded. The insulated case 30 is provided with a screw hole 33 for holding the other end of the circuit board 20 on the body of a product. As the result of filling of the insulating filler 35, the other end is extremely heavier in weight than the one end side. The above method can hold the other end side without applying excessive stress to the circuit board 20. COPYRIGHT: (C)2007,JPO&INPIT
