Abstract: A coil device includes a core having a flange portion connected to winding core portions; wires wound around the winding core portions; and terminal electrodes fixed to the core. The terminal electrodes have wire connectable portions to which lead portions of the wires are connected. In the wire connectable portions, the lead portions are connected to the terminal electrodes at positions separated from an upper surface of the flange portion by a predetermined height.

Abstract: A coil device comprises a first wire connected to a first terminal; a second wire connected to a second terminal; a terminal block anchoring the first terminal and the second terminal; a bobbin including a first cylindrical portion wound around with the first wire and extending along a first axis, a second cylindrical portion wound around with the second wire and extending along the first axis, and a flange portion connecting the first cylindrical portion and the second cylindrical portion; and a core accommodated in the bobbin. The terminal block at least partly covers the flange portion of the bobbin.
