Magnetic shielding sheet for wireless power reception module, and wireless power reception module including the same

A wireless power reception module comprising:

• a wireless power reception antenna capable of a wireless power share (WPS) function for charging a battery of an electronic device that employs a permanent magnet;
• and
• a magnetic shielding sheet disposed one surface of the wireless power reception antenna,
• wherein the magnetic shielding sheet is the magnetic shielding sheet,
• wherein the magnetic shielding sheet has an overall thickness of 150 μm or less,
• wherein the magnetic shielding sheet comprises:
• a first sheet made of a magnetic material to shield a magnetic field;
• and
• a second sheet laminated as a monolayer on one surface of the first sheet by means of a bonding adhesive layer,
• wherein the first sheet is provided with a thickness of 60 to 120 μm, which is 2 to 6.7 times thicker than a thickness of the second sheet so as to serve as a main shielding sheet that shields a magnetic field, and
• wherein the second sheet is provided with a thickness of 18 to 30 μm, which is thinner than a thickness of the first sheet while having a saturation magnetic flux density of 1 tesla (T) to 2T, which is twice or more than a saturation magnetic flux density of the first sheet of 0.2 to 0.5 T, so as to prevent magnetic saturation by the permanent magnet when the WPS function is performed, and supplement the shielding performance of the first sheet to increase the charging efficiency of the electronic device such that the total thickness of the magnetic field shielding sheet can be 150 μm or less.
