PROBLEM TO BE SOLVED: To obtain an inexpensive shield material for electromagnetic waves easily handleable and excellent in long term stability. SOLUTION: This net for electromagnetic shields and the sheet for electromagnetic shields are composed of soft magnetic metallic glass alloy essentially consisting of one or >= two kinds of elements among Fe, Co and Ni, contg. one or >= two kinds of elements among Zr, Nb, Ta, Hf and Mo, and B, and in which the temp. intervalδTx in the supercoolant liq. region expressed by the equation ofδTx=Tx-Tg (where Tx denotes the crystallization starting temp., and Tg denotes the glass transition temp.) is regulated to >=20 deg.K.
