摘要： A coil component ensuring adhesive bonding between first and second cores. The coil component also includes an inductive component and a pair of terminal electrodes. The first core has a first adhesion surface. The second core is connected to the first core by an adhesive agent and has a second adhesion surface in confrontation with the first adhesion surface. At least one of the first adhesion surface and the second adhesion surface is formed of a glass surface layer to which the adhesive agent is applied. The inductive component is wound over the first core. The pair of terminal electrodes are provided at one of the first core and the second core. The inductive component has one end portion electrically connected to one of the terminal electrodes and has another end portion electrically connected to remaining one of the terminal electrodes.

摘要： A coil component comprises: a core having a winding core portion, and a first flange and a second flange arranged at both ends of the winding core portion; a winding arranged in a region flanked by the first and second flanges, and wound so as to be in contact with the winding core portion; and a cover portion arranged in a region flanked by the first and second flanges, so as to cover the winding. The cover portion has a first cover portion comprising a resin cured product containing a magnetic material; and a second cover portion comprising a non-magnetic material. The second cover portion is interposed at least between the first flange and the first cover portion.

摘要： A coil component which can secure the insulation and strength of a ferrite core and reserve a winding region sufficiently is provided. By coating a surface of an Mn—Zn-based ferrite core with a glass film, this coil component can secure the insulation between the ferrite core and a terminal electrode. Coating with the glass film also ensures the strength of the ferrite core, thereby inhibiting cracks from occurring in boundary parts between a winding core part and flanges. In the coil component, at least one of the thickness of the glass film covering the surface of the winding core part and the thickness of the glass film covering the inner side face of the flange is smaller than the thickness of the glass film in the remaining part. Thus suppressing the thickness of the glass film on the surface of the winding core part and on the inner side face of the flange can sufficiently secure a winding region M.
