PROBLEM TO BE SOLVED: To provide a constant frequency power supply device which a choke coil is provided inside and has merits such as decrease in the number of components, reduction in cost, reduction in space, and the like. SOLUTION: The constant frequency power supply device of the invention is applied to a switching type circuit comprising a primary side and a secondary side. The constant frequency power supply device comprises a first iron core 1, a second iron core 2, a first line table 3, and a second line table 4. The first iron core 1 and the second iron core 2 are provided at positions opposing to each other. The cores have a first convex body 11 and a second convex body 21, respectively. The first line table 3 is positioned on the first convex body 11. The first line table 3 is provided with a first group linear coil 31 in a surrounding manner. The communication connection of the first group pin 32 of the primary side is carried out. The second line table 4 is positioned on the second convex body 21. The second line table 4 is provided with a second group linear coil 41 in a surrounding manner. The communication connection of the second group pin 42 of the secondary side is carried out. The first line table 3 is further provided with a fitting hole 35 for fitting the second line table 4. The first line table 3 and the second line table 4 form sliding telescopic motion connection using the fitting hole 35. Position locomotion is carried out on the first convex body 11 and the second convex body 21. Further, adjustment is added to inductance between the primary side and the secondary side.
