A magnetic shield structure having openings, the structure comprising a plurality of similar magnetic blind bodies 2 , each blind body 2 having an imaginary blind core plane F and a plurality of magnetic material slats 1 being spaced from each other by a distance d required for magnetic shielding, each slat 1 intersecting the blind core plane F at a longitudinal central axis C thereof, the longitudinal central axes of the slats are oriented substantially in parallel to each other on the blind core plane F. The blind bodies 2 a, 2 b are coupled in a row by serially coupling each slat 1 in each blind body 2 a to a corresponding slat 1 of adjacent blind body 2 b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2 a, 2 b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2 a, 2 b form openings in the magnetic shield structure. Preferably, three or more magnetic blind bodies 2 are coupled in a row so as to form a closed magnetic path. The blind bodies 2 a, 2 b may be stacked side by side in such a manner that the blind core plane Fa, Fb are parallel to each other and orientation of the slat central axes in each blind body 2 a, 2 b being selected so as to optimize attenuation of magnetic field across the magnetic shield structure.
