Patent ID: 8723632

Claim:
A coil component comprising: a magnetic substrate made of magnetic ceramic material; a thin-film coil layer containing a coil conductor formed on a principal surface of the magnetic substrate; a plurality of bump electrodes formed on a principal surface of the thin-film coil layer; and an insulating resin layer formed on the principal surface of the thin-film coil layer excluding formation positions of the bump electrodes, wherein the magnetic substrate, the thin-film coil layer and the insulating resin layer form a layered product, each of the bump electrodes has an exposure surface on a bottom surface and on two side surfaces of the layered product, the thin-film coil layer contains a plurality of terminal electrodes of the coil conductor, each of the terminal electrodes is connected to a corresponding one of the bump electrodes and has an exposure surface on at least one of the two side surfaces of the layered product, each of the terminal electrodes has smaller in size than the corresponding one of the bump electrodes in planar view, each of the terminal electrodes includes a first electrode portion connected to the coil conductor without being connected via the corresponding one of the bump electrodes and a second electrode portion connected to the coil conductor via the corresponding one of the bump electrodes, the first electrode portion has the exposure surface on one of the two side surfaces, and the second electrode portion has the exposure surface on the other of the two side surfaces.
