PROBLEM TO BE SOLVED: To obtain the contactless module which has less possibility of short- circuiting and is easy to handle. SOLUTION: This module 10 consists of a thin sheet 35, an IC substrate 11 fitted with electronic components, and a flat plate type coil 21; and the sheet 35 is almost as large as the coil 21, the IC substrate 11 is fixed almost in the center of the sheet 35, and the coil 21 is fixed to the sheet 35 while the external shape of the sheet 35 is made nearly to conform with the external shape of the coil 21. The inner peripheral end part 23 of the coil 21 is connected to the IC substrate 11 which is arranged in the internal space of the coil 21, the outer peripheral end part 25 of the coil 21 is positioned between the sheet 35 and coil 21, led out to the internal space of the coil 21, and connected to the IC substrate 11, and the internal space of the coil 21 is filled with sealing resin 31. |
