Abstract
The metallic sheet for shadow mask comprises a Fe-Ni alloy sheet having mainly of Fe and Ni; degrees of planes on a surface of the alloy sheet, the degree of {331} plane being 14% or less, the degree of {210} plane 10% or less and the degree of {211} plane 10% or less; and a ratio of degrees of planes which is {210}/[{331}+{211}] being 0.2 to 1. Another thin metallic sheet for shadow mask comprises a Fe-Ni alloy sheet having mainly of Fe and Ni; degrees of planes on a surface of the alloy sheet, that of {111} plane being 5% or less, that of {100} plane 50 to 93%, that of {110} 24% or less, that of {311} plane 1 to 10%, that of {331} 1 to 14%, that of {210} plane 1 to 10% and that of {211} plane 1 to 10%; a ratio of degrees of planes which is [{100}+{311}+{210}]/[{110}+{111}+{331}+{211}] being 0.8 to 20.
