This paper reports on a double winding micro coil as a receiver for MRI (Magnetic Resonance Imaging). A double winding micro coil was fabricated by assembling 3D printed structure and the flexible substrate wiring fabricated by MEMS (Micro Electro Mechanical Systems) technology. This micro coil has low parasitic capacitance because we could increase the gap between wirings. Furthermore the number of turns per unit length of this micro coil was increased by double winding wiring. The parasitic capacitance of fabricated micro coil at the frequency of 85.8 MHz was measured at 1.33 pF. The parasitic capacitance of fabricated coil decreased 24 % compared to the parasitic capacitance of comparison coil. The ratio of signal to noise of fabricated coil was 16.
