Claim:
1. An antenna module that is incorporated in an electronic device and becomes communicable in response to a magnetic field transmitted from a transmitter, the antenna module comprising: an antenna coil that is arranged on an outer peripheral part of a housing surface and is configured to face the transmitter and electromagnetically couple to the transmitter; and a magnetic sheet configured to attract a magnetic field transmitted from the transmitter to the antenna coil, the magnetic sheet being superimposed with the antenna coil in a direction orthogonal to the housing surface such that the magnetic sheet is between the antenna coil and the housing surface on an outer peripheral side and the antenna coil is between the magnetic sheet and the housing surface on a center side; the antenna coil including: the first and second coils being connected in one of a series connection and a parallel connection, the first and second coils being superimposed in the direction orthogonal to the housing surface such that approximately half or less of areas of the first and second coils are superimposed and portions of each of the first and second conductive lines are superimposed.
