PROBLEM TO BE SOLVED: To provide an inductance element which can attain the sufficient improvement of a heat dissipation property and low impedance to a high frequency current. SOLUTION: An inductance element 1 is provided with three lines of electric insulating core bodies 7 extended on an insulating board 2 along the longitudinal direction of coils 5, 5. The coils 5, 5 are formed by mutually connecting each plating layer 8 formed to cover each electrical insulating core body 7 by an electrolytic plating method. Consequently, the bottom side of the coils 5, 5 is irregular along the side surface and the top surface of the electrical insulating core body 7, and the top surface side of the coils 5, 5 is an arch-like irregular shape centered on each electrical insulating core body 7. Consequently, since a surface area of the coils 5, 5 is enlarged in the inductance element 1, it is possible to attain the improvement of the heat dissipation property of heat generated in the coils 5, 5 and low impedance to a high frequency current.
