A chip inductor is made up of a coiled conducting wire and a magnetic member which is formed by sintering and in which the coiled conducting wire is embedded. Both end portions of the coiled conducting wire are exposed to both end surfaces of the magnetic member. External electrodes are formed with conducting thin films and are connected to respective end portions of the coiled conducting wire. An inorganic material is interposed in a clearance between winds of both end portions of the conducting wire and external surfaces of the magnetic member and a clearance between adjoining winds of the conducting wire.

Provided is an electronic material composition which is capable of forming a cured film exhibiting a desired glass transition temperature, a desired stiffness modulus in a rubbery state and a desired extensibility at low temperatures. Also provided is an electronic component comprising a molded body, a packed body, a covering body, an electrode or a joining body, all being formed of the aforementioned electronic material composition. Also provided is a method of using the aforementioned electronic material composition, which is featured in that the electronic material composition is applied in a semi-cured state, and after the application thereof, completely cured.

A common mode choke coil adapted for surface mount applications minimized in overall size (particularly in height), with an improved bonding coefficient. This common mode choke coil has a structure comprising a ferrite core consisting of a winding core and two square planar flanges with recesses formed therein, the square planar flanges being formed integrally on each end of a winding core thereof, a pair of external electrodes disposed on the square planar flanges, a plurality of windings wound about the winding core of the ferrite core and connected by thermal bonding to the external electrodes at the recesses provided in the left and right sides of each flange, and a ferrite plate adhesively bonded to the outermost surface of the windings to join the two flanges at both ends of the ferrite core, without an adhesive bonding to the flanges themselves. As a result, a closed magnetic circuit structure of a cubic component having a high rate of bonding coefficient is obtained.
