摘要： Provided is a magnetic sheet including a resin film and a thin sheet-shaped magnetic body adhered to the resin film by an adhesive layer sandwiched between the thin sheet-shaped magnetic body and the resin film. The thin sheet-shaped magnetic body is made from an Fe-based metal magnetic material, has a thickness of 15 μm to 35 μm, and has an AC relative magnetic permeability (μr) in the range of 220 to 770 at a frequency of 500 kHz.

摘要： A near-field communication antenna comprising at least one annular coil, a planar, non-magnetic resin member holding the annular coil, a planar, soft-magnetic member overlapping the non-magnetic resin member via the annular coil, and terminals to which the conductor wire leads of the annular coil are connected, the annular coil being received in a circumferential recess along the periphery of the non-magnetic resin member lest that it projects from the periphery of the magnetic member, and the conductor wire leads of the annular coil being connected to the terminals through notches provided in the peripheral edge of the soft-magnetic member.
