The invention discloses a method for manufacturing a charging coil. The method comprises the following steps of: carrying out stamping operation on a copper foil, punching an arc-shaped copper wire with a spiral shape on the copper foil, and reserving a connecting material point between the arc-shaped copper wires, and connecting the arc-shaped copper wire and the copper foil body together; fixingthe arc-shaped copper wire on the copper foil, and fixing the arc-shaped copper wire and the copper foil body together; and cutting the connecting material points so that the arc-shaped copper wiresare connected to form a continuous spiral coil. The beneficial effect is that after the punching operation, the connecting point is left between the curved copper wires, and the connecting point is used to connect the arc-shaped copper wire with the copper foil body, thereby preventing the arc-shaped copper wire from prolapsed in a state in which the copper foil is suspended. Before the connectingpoint is cut off, the arc-shaped copper wire on the copper foil is fixed without prolapse. After the connecting point is cut off, the arc-shaped copper wire can be completely connected to form a continuous spiral coil, thereby manufacturing the charging coil.
