PROBLEM TO BE SOLVED: To inhibit the deterioration of performance of each coil and enable easy manufacturing while saving a space when multiple coils, such as a coil for non contact radio communication and a coil for non contact power transmission, coexist.SOLUTION: A first coil for non contact power transmission 12 is disposed on a surface of a first magnetic material 11. A second magnetic material for non contact radio communication 21 is disposed at an area on the surface of the first magnetic material 11 which is located at the outer side of the first coil for the non contact power transmission 12. A second coil for the non contact radio communication 22 is disposed on a surface of the second magnetic material 21. In an inner peripheral part of the second magnetic material 21B, guide members 21g, protruding from four corners of the inner peripheral part, are formed for preventing misalignment from occurring between the first coil 12B and the second coil 22B during the assembly of a coil unit. Each guide member 21g is formed into an arcuate shape so as to fit a shape of the first coil 12B. |
