First claim
Opening claim text (preview).
The invention claimed is: 1. A coil device comprising: a core including a winding core part and a flange part provided on an edge of the winding core part, a coil part comprised of a wire wound on the winding core part, an electrode film having a wire connecting part where a wire edge of the wire is connected, and the electrode film is formed on a surface of the flange part, and a metal terminal is connected to a terminal fitting part and is formed on a surface of the electrode film at a place different from the wire connecting part, wherein the metal terminal is fixed to the flange part by an adhesion member, at a place where the electrode film is not formed. 2. The coil device according to claim 1 , further comprising a plate member having a flat external face. 3. The coil device according to claim 1 , wherein the metal terminal comprises: a mounting part faced and connected to a surface of a circuit board, and a mounting assistance part formed continuously from the mounting part. 4. The coil device according to claim 3 , wherein the mounting part is disposed opposite to the wire connecting part respectively on the opposite sides of the flange part. 5. The coil device according to claim 3 , wherein the wire connecting part is disposed adjacent to the mounting part on the same side of the flange part. 6. The coil device according to claim 5 , wherein a pair of the metal terminals are provided on the flange part, and the wire connecting part is disposed between a pair of the mounting parts respectively formed on the pair of the metal terminals.
