摘要： A steel sheet for an inner magnetic shield has a ratio of the anhysteretic magnetic permeability in the rolling direction to the anhysteretic magnetic permeability in the transversal direction, which is not higher than 0.7 or not lower than 1.4, preferably not higher than 0.5 or not lower than 2.0. A higher value of the two anhysteretic magnetic permeability values in the rolling direction and in the transversal direction is not lower than 18000. The inner magnetic shield formed of the particular steel sheet has a substantially truncated pyramid body which has a pair of short side members of a screen and a pair of long side members of a screen. The short side members are joined to the long side members at edge portions of the truncated pyramidal inner magnetic shield. The direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to the horizontal plane direction of the short side member. In addition, the direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to as required to the horizontal plane direction of the long side member.
