ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2015/115318
Kind Code:
A1
Abstract:
Since each lead end of a coil is drawn perpendicularly to the surface of a molded article, the contact area between the lead end of the coil and an external terminal electrode will be determined by the thickness of the lead wire. Direct current resistance had tended to be large due to the joint between the lead end of the coil and the external terminal electrode. However, if the contact area between the lead end of the coil and the external terminal electrode is increased by increasing the thickness of the lead wire, there will have to be a increase in size in order to obtain a predetermined inductance value. The abovementioned problems are solved in the present invention, wherein a lead wire is wound to form a coil, and the coil is embedded in a molded article formed from a compound magnetic material containing magnetic powder and resin. The coil is formed such that each lead end thereof is cut obliquely with respect to the surface of the lead wire. The cut surface of each lead end of the coil is exposed on a surface of the molded article and connected to an external terminal electrode formed on the surface of the molded article.
