The invention relates to a magnetic field shield for electromagnetic fields, preferably in the frequency range of 50 Hz to 200 kHz, essentially comprising a composite plate (1) formed by at least three layers (1.1, 1.2, 1.3; 1.1, 1.21, 1.22, 1.31, 1.32) arranged one over the other, wherein at least one of the layers is made of electrical sheet or electrical strip. According to the invention, in order to economically create such a magnetic field shield having low weight and good shielding effect, at least one of the layers is made of steel sheet and at least one of the layers is made of plastic and/or elastomer, wherein the at least one layer (1.3; 1.31, 1.32) made of plastic and/or elastomer connects the at least one layer (1.1) made of electrical sheet/electrical strip and the at least one layer (1.2; 1.21, 1.22) made of steel sheet to each other in a bonded manner.
