It is main problem that improvement of the power transfer efficiency of Wireless Power Transfer (WPT) system. To realize a high quality factor coil we investigated the structure of the superconducting bulk coil. We obtained 30 times higher quality factor than the copper coil by optimizing the line width and gap between lines of the superconducting coil. We also simulated the coil quality factor with dielectric supporting material. To obtain high quality factor coil we have to use small dielectric loss supporting material which is less than 10^-6. We will present the detail of the preliminary experiments using superconducting bulk coil at the conference.
