A coil component according to one or more embodiments of the present invention includes: an insulating base body having a bottom surface; a coil conductor disposed in the base body and having a coil surface opposed to the bottom surface; and a reinforcement portion disposed in the base body. The reinforcement portion is disposed at a position closer to the bottom surface than is a middle point between the bottom surface and the coil surface.

Coil component

In an exemplary embodiment, an electronic component includes: an element body partconstituted by an insulative body of rectangular solid shape; an internal conductorprovided inside the element body part; and external electrodesprovided at least on the bottom face(mounting surface) of the element body partand electrically connected to the internal conductor; wherein the element body parthas: a conductor-containing layerin which a coil conductor(functional part) that will become a part of the internal conductorto demonstrate electrical performance, is provided; and a high-hardness layerwhich is provided side by side with the conductor-containing layerin a direction parallel with the bottom face(mounting surface) of the element body part, and which has a higher hardness compared to the conductor-containing layer. The electronic component has improve mechanical strength.

The electronic component has improve mechanical strength.

One object is to compensate the reduction of the Q value due to reduction of core sectional area of a coil of an inductor, and the reduction of positional accuracy and adhesive strength of components mounted on a printed circuit board due to reduction of area of external electrodes, both caused by downsizing of component sizes. An inductor is provided which includes: a coil formed in an insulator and having one end and the other end thereof formed in a direction away from a mounting surface; and lead-out portions connected to the coil at positions more distant from the mounting surface than a portion of the coil closest to the mounting surface.
