<p>PURPOSE:To obtain an inductance coil by screen printing as well as reduce its cost by forming a coil-shaped conductor wiring on a substrate of ceramic or the like, using an insulator as a core. CONSTITUTION:On an insulative substrate 1 of ceramic or the like, the lower conductor 2 is printed by screen printing and sintered. Then, an insulator 3 and the upper conductor 4 are printed and sintered. Thus, the conductor wiring is formed into a coil shape in order to obtain inductance characteristics. Moreover, the lower conductor 2 and the upper conductor 4 are interconnected by piling the patterns one upon another outside the insulator 3. Thereby, allowance is provided for circuit design, and the production costs can be reduced.</p> |
