A heat shrink band steel sheet of the present invention comprises on the basis of percent in weight C: 0.1% or less, Si: 0.1% or less, Mn: 0.1 to 2%, P: 0.15% or less, S: 0.02% or less, sol Al: 0.08% or less, and N: 0.005% or less, or C: 0.005% or less, Si: 0.1% or less, Mn: 0.1 to 2%, P: 0.15% or less, S: 0.02% or less, sol Al: 0.08% or less, N: 0.005% or less, Ti: 0.02 to 0.06%, and B: 0.0003 to 0.005%, wherein the product of a magnetic permeability at the magnetic field of 0.3 Oe after heat shrinking treatment and a thickness (mm) is at least 350. A color CRT having a sufficient magnetic shielding characteristic and a less amount of color deviation can be realized by the steel sheet.
