PROBLEM TO BE SOLVED: To provide an antenna module stabilizing communication characteristics of a communication apparatus by suppressing dispersion of a resonance frequency even by an inexpensive structure using a single-sided board.SOLUTION: This antenna module is structured such that: a substrate 1 of an insulating material has inner and outer circuit regions partitioned by a loop antenna 5; at least one side of terminal parts 9 of the loop antenna 5 has, in the middle of a line, a jumper wire part 8 aligned and extracted to the same circuit region as that of the other side of the terminal parts 9 by straddling the loop antenna 5; the jumper wire part 8 is formed by print of conductive paste interposing an insulation film having a thickness of 50-600 μm between the loop antenna 5 and itself; and an insulation protective layer is formed on one surface of the substrate 1 arranged with the loop antenna 5, excluding the terminal parts 9. |
