摘要： An in-line type electron gun (4) using a field superimposing type main lens system is provided that can attain good focusing properties by decreasing the size of the electron beam spot on the entire surface of the phosphor screen (5) without being formed to be mechanically large. A field superimposing type main lens is formed by disposing two tubular electrodes (14) opposite to each other and disposing a plate-like field correction electrode (10) on each of the tubular electrodes (14) on the sides not opposite to each other. On each of the opposite sides of the two tubular electrodes (14), an opening is formed by an edge portion (12) and a folded portion (13). The shape of the opening may be an elongated flat-sided oval shaped aperture (laterally elongated aperture) that is formed by straight lines and semicircles and has a major diameter in the horizontal direction and a minor diameter in the vertical direction. The in-line type electron gun (4) is configured such that a relationship B
