摘要： An internal magnetic shield reduced in mistaken landing length due to distorted electron beams by the external magnetic field of geomagnetism or the like, and also reduced in color misregister and color unevenness. The internal magnetic shield is provided with at least one skirt unit (37) in an externally square tube shape having a plurality of side surface and extending from a non-contact portion with a holding member (42) up to the vicinity of a tension member (41), the skirt unit (37) being magnetically coupled with the tension member (41) constituting a mask frame.
