Color cathode-ray tube

A color cathode-ray tube, comprising:

• a panel;
• a funnel connected to the panel;
• an electron gun provided in a neck of the funnel;
• and a substantially rectangular shadow mask in a dome shape provided so as to be opposed to an inner surface of the panel,
• wherein the shadow mask has a plurality of tie-bands with a longitudinal direction thereof being a short-side direction of the shadow mask, a plurality of bridges connecting the tie-bands adjacent to each other in a long-side direction of the shadow mask, and a plurality of electron beam passage apertures formed between the tie-bands adjacent to each other in the long-side direction,
• in a region sandwiched by a pair of straight lines parallel to the long-side direction, which respectively pass through a pair of the bridges adjacent to each other in the short-side direction, on a surface of the tie-band on a side opposed to the electron gun, a plurality of non-through concave portions are formed, and
• a depth of the concave portion is larger at a position in a vicinity of an end on the electron beam passage aperture side in the concave portion, compared with a depth at a position in a vicinity of an end on a center side of the tie-band in the concave portion, in the long-side direction.
