Abstract:
To achieve a reduction of noise in a wireless system of an electronic device for communication. The electronic device for communication includes: a bottom lid; a loop antenna that forms an electromagnetic field; a communication circuit coupled to the loop antenna; a battery pack that is a metallic part; a magnetic sheet arranged between the loop antenna and the metallic part, the magnetic sheet including a protruding portion that protrudes outside an outer peripheral portion of the loop antenna; a wiring substrate arranged over the battery pack and having an IC and the like mounted thereon; and a lid with a display arranged over the wiring substrate, in which, with the outer peripheral portion of the loop antenna as a base point, a protruding amount from the base point of the protruding portion of the magnetic sheet is twice or more a wiring width of the loop antenna.
