The production methods and the electric characteristics of coils made by the use of sewing technology were described. These coils were assumed to be used in magnetic coupling of wireless power transmission for small electronic devices. The sewed coil was produced using two methods of a cross-stitch and a conventional sewing machine. The inductance of one of the sewed coil was measured and compared with the Qi coils. The coupling coefficients between a Qi receiver coils were measured. The maximum coupling coefficient was 0.78. The power efficiencies were measured to be 76% for 10-ohm load resistance. We showed that the sewed coil could be used as the transmitting coil for small electronic devices.
