An in-line stripe type color picture tube comprises an inner magnetic shield member having sufficient shield effect against both individual vertical and horizontal components of the earth magnetism and composite components as well. The inner magnetic shield member prevents unwanted shifts of electron beams to ensure that the positional relationship between a fluorescent screen and landing electron beams may have sufficient tolerances and color blur on the fluorescent screen may be prevented.
