Abstract
A heat-insulating panel serving also as a concrete frame excellent in bending strength characteristics and dimensional stability and a method of manufacturing the panel. Cut or shredded pieces having lengths of 20 mm or less of magnetic tapes are heated to 100.degree. to 200.degree. C., thus forming contracted pieces of magnetic tapes in curled shapes. The curled contracted pieces of magnetic tapes in an amount of 100 parts by weight are mixed with 10 to 50 parts by weight of a thermosetting resin as a binder, and are compression-molded under a pressure ranging from 2 to 20 kgf/cm.sup.2 at a temperature from 100.degree. to 200.degree. C.
