INDUCTOR COMPONENT AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2017/130462

A1

The present invention improves the characteristics of an inductor component by lowering the resistance of an inductor electrode. An inductor component 1a comprises a resin layer 3 and an inductor electrode 6, wherein the inductor electrode 6 has metal pins 7a-7d that are provided to the resin layer 3 such that one end surface 70a-70d of each of the metal pins 7a-7d is exposed at an upper surface 3a of the resin layer 3, and upper side wiring boards 8a, 8b that are positioned on the upper surface 3a of the resin layer 3 and connect the end surfaces 70a, 70c of the shorter metal pins 7a, 7c and the end surfaces 70b, 70d of the longer metal pins 7b, 7d. The longer metal pins 7b, 7d are formed thicker than the shorter metal pins 7a, 7c. Because, in this case, the inductor electrode 6 is formed from the metal pins 7a-7d and the wiring boards 8a-8c, all of which have lower specific resistances than conductive paste or plating, the resistance of the entire inductor electrode 6 can be reduced, thereby improving the characteristics of the inductor component 1a.
