Abstract
A coil component according to one or more embodiments of the invention includes a base body, a coil conductor embedded in the base body, and an external electrode provided on the base body. The base body has on its surface a first region that has a first reflectance, a second region that has a second reflectance lower than the first reflectance, and a third region that is surrounded by the second region and has a third reflectance higher than the second reflectance. The third region has a shape of a sign.

A coil component comprising:
- a base body having on its surface a first region that has a first reflectance, a second region that has a second reflectance lower than the first reflectance, and a third region that is surrounded by the second region and has a third reflectance higher than the second reflectance, the third region has a shape of a sign;
- a coil conductor provided in the base body;
- and
- an external electrode provided on the base body.
A method of manufacturing a coil component, comprising:
- fabricating a blank body from a magnetic material, the blank body including a conductor thereinside and having a surface that has a first reflectance;
- forming a low reflectance region in a part of the surface of the blank body, the low reflectance region having a second reflectance lower than the first reflectance;
- and
- forming a sign region in the low reflectance region, the sign region having a third reflectance higher than the second reflectance and having a shape of a sign.
A method of manufacturing a coil component, comprising:
- fabricating a blank body from a magnetic material, the blank body being defined by a surface having a first reflectance;
- forming a low reflectance region in a part of the surface of the blank body, the low reflectance region having a second reflectance lower than the first reflectance;
- forming a sign region in the low reflectance region, the sign region having a third reflectance higher than the second reflectance and having a shape of a sign;
- and
- winding a wire around the blank body.
