ELECTRONIC DEVICE AND ANTENNA DEVICE

摘要

An electronic device and an antenna device are provided that use a coil module which is thinned without losing the characteristics of the coil module and which can be mounted in a narrowed space. A coil module (1) including a loop-shaped antenna coil (5) wounded in a planar shape and a sheet-shaped magnetic sheet (4) which is formed of a magnetic material and which overlaps with at least a part of the antenna coil (5) is included. In the coil module (1), a part of the antenna coil (5) is overlapped with an internal structure (10) of a housing and the magnetic sheet (4) is provided in a position that does not overlap with the internal structure (10) on an antenna coil (5) surface side that overlaps with the internal structure (10).
