PROBLEM TO BE SOLVED: To provide a winding method of a coil which enables multilayer alignment winding, is suitable for miniaturization of a coil and hardly damages a coil. SOLUTION: In the winding method of a coil for winding an insulation electric wire 4 around a coil bobbin 3 provided with brim parts 2, 2 formed in a winding part 1 and both ends of the winding part 1, a slit 5 at an acute angle relative to a longitudinal central axis X of the coil bobbin 3 is formed at least in one of the brim parts 2, 2, a winding start side S of a coil is led into the winding part 1 from the slit 5, and the winding start side S of a coil is led out of the slit 5 to the coil outer circumferential direction by winding the insulation electric wire 4 around the winding part 1. |
