PURPOSE: To form insulator layers on conductor patterns so as to be flat in such a way that the formation process of the insulating layers is simple and that a defect such as a pinhole or the like is not caused by a method wherein the insulator layers are formed in such a way that an insulator paste from a fine discharge port is coated and formed continuously in a belt shape inside a plurality of sections.
CONSTITUTION: In a process in which insulator layers and conductor patterns are laminated and formed repeatedly, an insulator paste is discharged from a plurality of fine discharge ports in a belt shape in individual rows in a plurality of sections on an insulator sheet 50 having the plurality of sections by using a discharge device 40 provided with the individual discharge ports, and the insulator layers 51 which are belt-shaped are coated and formed continuously. Then, the insulator layers on the conductor patterns can be formed in such a way that the formation process of the insulator layers is simple and that a defect such as a pinhole or the like is not caused. Thereby, the conductor patterns whose definition is high can be printed and formed, the insulator layers whose number is many can be laminated, and it is possible to obtain the inductor whose yield is high, which is small and whose inductance value is large.
