The invention provides an inductance coil and a laser-cutting manufacturing method of the inductance coil. The inductance coil comprises an upper copper foil coil, a lower copper foil coil, a heat-resistant organic thin film and magnetic material layers, wherein the outer surface of the upper copper foil coil and the outer surface of the lower copper foil coil are provided with insulating coatings for insulating treatment, the heat-resistant organic thin film is arranged between the upper copper foil coil and the lower copper foil coil, and the magnetic material layers wrap the periphery of the upper copper foil coil and the periphery of the lower copper foil coil. Coil patterns of the upper copper foil coil and the lower copper foil coil are formed through cutting by a laser light source. The insulating coatings are heat-resistant coatings. The magnetic material layers are formed through compression molding, and a magnetic material is iron metal alloy soft magnetic powder. The laser-cutting manufacturing method comprises laser cutting on the upper copper foil coil, the lower copper foil coil and the heat-resistant organic thin film. The inductance coil is formed by copper foil in a laser-cutting mode, parameters including line width, thickness, distance between lines, coil center pillars and the like can be adjusted to form the coil patterns on normal positions, and target characteristic specifications can be designed quite easily. The inductance coil and the laser-cutting manufacturing method of the inductance coil overcome the shortcomings that an existing inductance coil is difficult to fix and loses efficacy in an open circuit and a short circuit, and end electrodes are difficult to design, and better accord with the development tendency that a power inductor is small, thin and low in cost.
