<p>PROBLEM TO BE SOLVED: To provide a coil device in which the efficiency of a magnetic field generated by a coil can be ensured.SOLUTION: A solenoid 1 includes a resin bobbin 6, and a substantially annular coil 7 wound around the bobbin 6. The bobbin 6 is provided with coil end fitting portions 11 becoming the start-of-winding and end-of-winding portions of a coil winding. A winding connection 34 formed by winding the coil winding around terminals 13, 16 at the coil end fitting portions 11 is arranged on the outside of a magnetic path R generated from the coil 7. It can be obtained by attaching a U-shaped yoke 5 to the side face of the bobbin 6.</p> |
