Abstract: A magnetic sheet having improved acid/base-resistant properties, corrosion-resistance, and an excellent magnetic property at NFC, WPC, and MST frequencies, has little changes in weight and thickness even if the environment changes, for example, even after an etching treatment for patterning, or a reflow or soldering process which is performed for its application to a product.
