A solenoid is provided to make work easy by making a conductor of a coil equal to a width of a bobbin and increase an efficiency of device by minimizing the loss of magnetic flux. A solenoid includes a thin film conductor(100) for a coil, a bobbin(200), and a core(300). The thin film conductor is installed on the bobbin. A pair of drawing conductors(800,900) are installed at both sides of the thin film conductor and have a structure to be safely guided to an outside of the bobbin. The core has a structure having an incision unit(307) at a central part to be installed after finishing the solenoid thin film conductor. The core has an elongated arm(308) to extend an effect of magnetic field after end portions of the core maintains a predetermined interval(309).
