Title:
MANUFACTURE OF INDUCTANCE ELEMENT
Document Type and Number:
Japanese Patent JPS5928304
Kind Code:
A
Abstract:

PURPOSE: To obtain the small-sized inductance element of high Q by forming a conductive layer in sufficient thickness and reducing resistance.

CONSTITUTION: Ferrite 24 is printed on a ferrite layer 21 by using a mask 22 except the section where a conductive layer is formed. The conductive layer 23 is printed by using a mask 25. The mask 25 is formed in a pattern reverse to the mask 22. Conductive paste is printed to the section surrounded by the ferrite 24 and the upper section of said section. The conductive layer is formed, and ferrite 26 is printed on the conductive layer 25 and the ferrite 24. The process is repeated in succession, these layer and ferrite are laminated until the number of the conductive layers wound reaches a fixed number, and the whole is baked. Since the conductive layers are printed thickly at that time, sufficient thickness is kept even when they are shrunk through sintering. According to the manufacture, the thickness of the electrode of the element can be taken in a sufficiently large value. Consequently, the resistance of the electrode can be reduced, and high Q can be obtained.
