    摘要: An electronic component including a magnetic member comprising an iron oxide magnetic composition, a nonmagnetic member in contact with the magnetic member and including a glass ceramic composite composition, and an internal conductor portion disposed in at least one of the magnetic member and the nonmagnetic member. The glass ceramic composite composition includes crystallized glass as a main component, and quartz as a sub-component filler. The crystallized glass contains 25 percent by weight to 55 percent by weight of SiO2, 30 percent by weight to 55 percent by weight of MgO, 5 percent by weight to 30 percent by weight of Al2O3, and 0 percent by weight to 30 percent by weight of B2O3, and the content of the quartz is 5 percent by weight to 30 percent by weight relative to 100 percent by weight of the crystallized glass.

    摘要: A conductor pattern for forming coils and lead-out electrodes which are led out from the coils are formed on a magnetic substance sheet. Furthermore, said magnetic substance sheet is provided with through-holes for connecting the conductor patterns. The magnetic substance sheets disposed respectively just over and just under the conductor pattern that becomes the lead-out electrodes are coated with non-magnetic material paste. A laminated chip common mode choke coil is produced by laminating these magnetic substance sheets and baking them integrally and thereafter forming external electrodes. The non-magnetic material diffuses into the magnetic substance sheet by baking the lamination of the magnetic substance sheets, and the permeability of that portion becomes low. Therefore, the magnetic reluctance around the lead-out electrode becomes high, thus reducing leakage flux around that portion. Thereby, coupling between two coils formed in the choke coil becomes good.
