In a shadow mask 1 of pressing type, a large number of slots are made in a
mask body in the horizontal direction and in the vertical direction. Each
slot has a roughly rectangular backside opening, a roughly rectangular
front-side opening, and a through-hole that connects these two openings.
Between each slot of the multiple slots made in the mask body that is
situated at least on either of the two diagonal axes of the mask body but
in such a position that the angle at which electron beams enter the slot
is 20 degrees or more and another slot that is arranged adjacently to the
above slot in the vertical direction, a connecting part connecting the
peripheral-side vertical outer edges of the front-side openings of these
slots is provided so that it runs through a horizontal bridge part formed
between the front-side openings of the slots.
