Coil component and method for manufacturing same

A coil component comprising:

• a magnetic body containing soft magnetic alloy grains;
• and a conductor embedded in the magnetic body or placed on the surface of the magnetic body;
• the coil component characterized in that the magnetic body contains, as soft magnetic alloy grains, first grains whose alloy components are substantially or consists essentially of Fe, Si, and Cr, as well as second grains which contain, as alloy components, Fe, Si, and an element other than Si or Cr that oxidizes more easily than Fe;
• wherein,
• the first grains and the second grains are mixed throughout the magnetic body;
• the first grains and the second grains are different in that the first grains have, on their surface, an amorphous oxide film containing Si and Cr, whereas the second grains have, on their surface, a layer of crystalline oxide containing the element other than Si or Cr that oxidizes more easily than Fe;
• and
• the crystalline oxide forms adhesion parts, each contacting a multiple number of the first grains via the amorphous oxide film thereof and coupling or bridging the multiple number of the first grains throughout the magnetic body.
