PURPOSE: To acquire a small-sized light-weight high-mass productivity magnetic shielding material having a complicate shape by mixing and dispersing fillers into an organic matrix.

CONSTITUTION: Powdered, flaky or fibrous fillers consisting of a superconductive substance are mixed and dispersed into an organic matrix. An LA-Ba-Cu-O, La-Sr-Cu-O or R-Ba-Cu-O (R represents Y, Nd, Sm, Eu, Gd, Tb, Ho, Dy, Yb, Er, Lu) system is preferable as the superconductive substance used. An epoxy resin, a thermoplastic polyamide resin, etc., capable of being employed up to a very low temperature is desirable as the organic matrix. Accordingly, a superconductive magnetic shielding material, which has a complicate shape, can be lightened and miniaturized and has high mass productivity, is acquired.
