摘要： Disclosed herein is a coil component that includes a core including a winding core part extending in the x-direction and a flange part, a terminal electrode provided on the flange part, and a wire wound around the winding core part and connected to the terminal electrode. The terminal electrode does not overlap the winding core part in the y-direction. The wire includes a wound part wound around the winding core part and a drawn part drawn from the wound part, running across the winding core part in the z-direction and connected to the terminal electrode. The core has a positioning part that positions the drawn part of the wire in the y-direction.

摘要： A coil device includes a winding core, a wire, and a terminal fitting. The winding core is made of a magnetic material and includes a flange. The wire is wound around the winding core. The terminal fitting is attached to a part of an outer surface of the flange. The terminal fitting includes a contact part and a protrusion plate part. The contact part is contacted with the outer surface of the flange. The protrusion plate part is formed integrally with the contact part and protrudes away from the flange. The protrusion plate part includes a wire connection surface and a main mounting surface. A lead end of the wire is connected to the wire connection surface. The main mounting surface is located opposite to the wire connection surface and is connectable to an external circuit.

摘要： To provide a coil device having high bonding strength and bonding reliability.
The coil device 1 has a core member 10 having a winding core and a flange 12, a wire 32 wound around the winding core, and a terminal electrode 52 connected with a lead 32a of a wire 32 provided to the flange 12; and an easy bonding layer 70 is formed on the surface of the terminal electrode 52 connected with the lead 32a in a stripe form 70a. the stripe form each bonding layer 70a is formed as a laser mark 71. In the coil device 1, a residue of coating film 78 which may be generated when the lead 32a of the wire 32 is connected to the mounting part 65 of the terminal electrode 52 is removed by laser.-
