Abstract

Provided are a composite sheet for shielding a magnetic field and an electromagnetic wave, and an antenna module using the same, which can block influence of a magnetic field on a main body and a battery of a mobile terminal block device, and the like, and simultaneously shield an electromagnetic wave, by significantly reducing a loss due to an eddy current by flaking an amorphous ribbon sheet. The composite sheet includes: a magnetic sheet; and a conductor sheet stacked on the magnetic sheet for shielding an electromagnetic wave and radiating heat. The magnetic sheet includes: an amorphous ribbon sheet which is thermally treated, flaked, and then separated into a plurality of fine pieces; a protective film bonded to one side surface of the amorphous ribbon sheet; and an adhesive tape bonded to the other side surface of the amorphous ribbon sheet.
