PROBLEM TO BE SOLVED: To provide an antenna for noncontact charger which allows a high degree of freedom for the arrangement on the transmission side and reception side during charge, while preventing deviation of the resonance frequency of a receiving coil.SOLUTION: In an antenna sheet for noncontact charger used as a transmission side resonator or a reception side resonator, when the capacity of a resonance capacitor is C, a coil-like antenna functioning as a pickup coil resonating at a resonance frequency f is formed on a base material, a magnetic sheet is attached to the side of the base material opposite from the coil-like antenna, and a soaking sheet is attached to the magnetic sheet so as to sandwich the magnetic sheet with a substrate. |
