13. A mold of a case of an electronic device, the mold comprising:
-
upper and lower molds contacted with and supported by a radiator frame, the radiator frame injection molded using a polymer mixture containing a magnetic substance component so that a radiator including a low frequency antenna pattern part may be formed on one surface thereof; a resin material inlet formed in the upper mold, the lower mold, or in the upper and lower molds and having a resin material introduced thereinto so that a case frame shaped inner space formed by combining the upper and lower molds becomes a case frame; and a boundary part forming part provided to at least one of the upper and lower molds and having the radiator frame inserted thereinto. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of manufacturing a case of an electronic device, the method comprising:
-
injection molding a radiator frame using a polymer mixture containing a magnetic substance component so that a radiator including a low frequency antenna pattern part is formed on one surface thereof; allowing an outer circumferential surface of the radiator frame to be inserted into and seated in an inner side of a boundary part forming part formed in a mold of the case of the electronic device; and allowing a resin material to be introduced from an outer side of the boundary part forming part, pass through the boundary part forming part, be filled from an upper surface of the radiator frame and then be filled in a case frame shaped inner space formed in the mold of the case of the electronic device. - View Dependent Claims (27)
