Abstract
A masking material for use in a heating process includes: a base material comprising a resin as a main resin component and containing a magnetic substance, the resin having a higher melting point than a temperature of the heating process, the magnetic substance having a higher Curie temperature than the temperature of the heating process; and a releasable protective layer formed on one surface of the base material, the releasable protective layer comprising a releasable protective material. The masking material has excellent heat resistance property and can be repeatedly used.
